moved you to the rooting section as you will get more help with your questions here.

yes you will be able to do everything that a fully rooted phone can do and that includes removing bloatware. only difference really is that you will have a watermarked bootloader which voids your warranty(and that should not matter anyways as the evo is now eol).

you will have to be very careful as to what you delete though as some of the things might be needed in order for sense to work. best thing to do really is just flash a custom rom. roms like mikg3.11 is waaaaaaaaaaay better then stock and has all of the bloatware removed. here is the link to it:MikG v3.11 [3/9/2012]

here is a guide to help you:

and then once you have unlocked the bootloader and installed a custom recovery then i would also read this guide:http://androidforums.com/evo-4g-all...ooting-dummies-guide-gingerbread-edition.html. just follow the after root section. it has tons of info including how to properly flash a rom and also about making nandroid backups.

hope this help.

 

IMHO, if you held out this long w/out rooting, you will be amazed at your phone if you decide to root. I held out one year before rooting my EVO and when I finally did root it, it was like having a completely new phone. Plus, most of the custom roms do remove the bloatware for you. If you like the stock rom, you can get that, too.
