Sorry if it's cluttered.

1. I highly suggest you research and learn how to use ADB because it's extremely useful. ...Lucky for those that do not...or do not want to learn it there's this: http://www.rootjunky.com/debloater-tool-android/. I haven't used debloater extensively but I have tested it out with success. You should be able to block any system or third party application.

2. Disabling the Sony Enterprise Device Administrator: http://forum.xda-developers.com/z3-compact/help/deactivated-apps-getting-activated-t2889082

"Did some more research on that matter for I found this really annoying. Deactivated Apps shall remain deactivated, even more so for as long as we don't have root yet. Figured finally out (reproducible) that it's Disabling Device Administrators to trigger (some) Apps to get activated again.” (e.g. Chrome, google +, hangouts, file commander, sony video unlimited, sony select, etc)

In order to get rid of admins "Sony Enterprise API" and "Sony My Xperia" do the following: Download ADB and store it somewhere on you PC. Enable USB debugging on the phone and connect it to your PC. Disable the Sony Enterprise Admin under the security settings in your phone. Open a command window and navigate to where you stored ADB. Type "adb shell" at the prompt, hit ENTER and and the prompt changes to "shell@D5803:/ $" To block "Sony Enterprise API", issue command: "pm block com.sonymobile.enterprise.service" “Exit” in command prompt. Then “adb reboot” To block "Sony My Xperia", issue command: "pm block com.sonymobile.mx.android" Then reboot.

The result of the block commands should look like "Package %PACKAGE_NAME% new blocked state: true. If still "false", you have to deactivate the corresponding admin in the settings first and re-issue the command again.”

1. Disabling apps (For these you cannot block all three at the same time. Remove whats new, reboot, then remove small apps, then reboot): http://forum.xda-developers.com/z3-compact/development/mod-rootremove-whats-navring-small-apps-t2902419/page2

“You can use ADB on unrooted devices to remove the "What's New" option from the NavRing and to remove the Small Apps Widget launcher from Recent Apps.

I will assume you know how to install and use ADB.

To remove the "What's New" option from the NavRing: Code:

adb shell pm block com.sonymobile.advancedwidget.entrance exit adb reboot

Make sure to reboot before proceeding if you're removing both items. To remove the Small Apps Widget Launcher from the Recents screen: Code:

adb shell pm block com.sony.smallapp.launcher pm block com.sony.smallapp.app.widget exit adb reboot

To revert changes substitute "unblock" for "block" in the command.”

1. I’d say those previously mentioned are the main ones. Here’s a list for the rest of bloat. Don’t just blindly disable what’s on this list. I disabled the majority of this list and what applies to me, but left a few unblocked such as: pm block com.google.android.music (google play music). You could leave the small app launcher/widget if you like it.

adb devices adb shell pm block com.sonymobile.advancedwidget.entrance pm block com.sony.smallapp.launcher pm block com.sony.smallapp.app.widget pm block com.sonyericsson.textinput.chinese pm block com.sonymobile.simplehome pm block com.sonymobile.anondata pm block com.google.android.apps.books pm block com.google.android.music pm block com.google.android.videoeditor pm block com.google.android.videos pm block com.google.android.apps.genie.geniewidget pm block com.google.android.apps.uploader pm block com.facebook.katana pm block com.sonyericsson.idd.agent pm block com.android.stk pm block com.sonyericsson.eventstream pm block com.sonyericsson.eventstream.facebookplugin pm block com.sonyericsson.eventstream.twitterplugin pm block com.sonyericsson.eventstream.twitterpostviewer pm block com.sonyericsson.socialengine pm block com.sonyericsson.socialengine.plugins.facebook pm block com.sonyericsson.socialengine.plugins.picasa pm block com.sonymobile.socialengine.plugins.facebook_share frwk pm block com.sonymobile.socialengine.plugins.playmemories pm block com.sonymobile.socialengine.plugins.twitter_sharef rwk pm block com.sonyericsson.socialpane.friends pm block com.sonyericsson.facebook.postview pm block com.sonyericsson.facebook.proxylogin pm block com.sonyericsson.fbmediadiscovery pm block com.sonyericsson.androidapp.fbcalendarsync pm block com.sonyericsson.androidapp.fbmusiclike pm block com.sonyericsson.androidapp.fbsetupwizard pm block com.sonyericsson.androidapp.storefront pm block com.sonymobile.twitter.account pm block com.sonymobile.twitter.setupwizard pm block com.sonyericsson.advancedwidget.music pm block com.sonyericsson.advancedwidget.notewidget pm block com.sonyericsson.advancedwidget.photo pm block com.sonyericsson.advancedwidget.weather pm block com.sonyericsson.androidapp.timescapefeedsplugin pm block com.sonyericsson.video pm block com.sonyericsson.timescape.ui pm block com.sonymobile.mx.android pm block com.sony.snei.mu.phone pm block cjp.co.sony.tablet.PersonalSpace exit adb reboot

Many of the packages are self explained by its name but some arn't. Therefor I would recommend to do a quick search on the below posts to figure them out.
