There is a post about this, I would provide the link but I'm currently at work, I have deleted a lot, Google talk will sometimes give you trouble but 9/10 I haven't had any, you can also delete Calender and clock, and obviously the bloatware. But look for the post it should be on the first or second page of the "prevail all thing root" forums

 

while you should have used the search function first, I will still be kind enough to talk you through the basics... get root explorer or an equivalent from the market. browse to system/app and mount as read/write long press on the app you want to get rid of and click delete... I suggest backing up via cwm before doing this in case you screw up...

 

You can get a free version of Titanium Backup, but it is somewhat limited as to what all you can do with the options. The "donate" version of Titanium is around $6 or $7 dollars, but it is worth every cent. I'm not sure if there is a free version of Root Explorer anymore, but the "donate" version is right at $5. Both are indispensible tools when it comes to having a rooted phone, but since you are a beginner I would recommend Titanium Backup due to the ease of making backups and deleting bloatware.

 

Titanium backup will remove system apps easily. Ive only ever laid my eyes and hands on o smart phone a week ago for the first time when i bought the prevail and last night i rooted my phone and then backed it and removed all useless preinstalled apps. (and i did it all by myself without f-in up my phone lol Im so proud) anyhow titanium has a online how to book for dummys witch i followed step by step and was able to do it within a few mins last night. (best thing ever) Now all i need to do is read up on and figure out this custom rom and clocking stuff. (This is harder for me because i dnt understand any of it.) But here is where i went after downloading it: How To Use Titanium Backup For Android [Complete Guide]
