Stuck on Bootscreen!! Need Help ASAP

[ferncc21]

Well i have been searching all over this site and xda and still cant find the solution.
I have the Evo 4G. I am rooted to Myn’s Warm TwoPointTwo RLS 4 – (11/25/2010), great rom btw, Radio 2.15.00.07.28, but as of late when i over use my phone it has been turning off when im on youtube or searching something online, with and without the 4g.
Any who, today i have reached to a point in which it will not move from the boot screen. There is a new update on Myn's, all i want to do is to restore it to the RLS 4 and get my bookmarks, save text messages, new phone #'s and call log, so i can update it to RLS 5. Im using ClockworkMod but the previous version and i dont know what any of the options mean when trying to restore.

Thank you in advance, this phone is well my life!!! as most you may agree!
