Will this app get me firmware 3.52 M33 wihtout killing my PSP? and would this be the best firmware to get?

My PSP has firmware 2.71 and on the left hand side it has IC6001 and on the right hand side it has IC1003 on the motherboard. So I beleive I have a TA-082 motherboard.

It seems way to easy. Can someone confirm? Also how does this work? Do I flash it with the software and it copies the needed files to memory card and the next game I start the psp with the GTA unpatched game it installs the firmware?

I'm new to PSP hacking. Please help me.
