The removable of bloat boils down to personal preference and comfortableness messing with your phone and it's software. These are done via the phone.
- Light: Using Titanium Backup Pro. You can freeze system and bloat apps you don't want to use or have cluttering your menus. You can always unfreeze them restoring their functionality, and if you need to Factory Reset, you're good to go. It can also backup APKs and their related data (settings, etc).
- Medium: Using several methods including Root Explorer, delete the apks for what you don't want. Do not use the uninstall function in TBP. Factory Reset will not restore deleted system apps/bloatware. They must be reinstalled first. Note that some system apps will not go back into the phone easily, requiring a bit more work.
- All In: Follow all steps of rooting, including the installation of Custom Recovery. You then perform a NAND backup and can go buck wild, to an extent of course. You can also try out any of the available 2.2 ROMs floating around here.
