Modding my phone, Help please.

[Timmi]

Hello all, A bit about myself. I am 24 have a minor in applied computer science and love trying to mod all my computer toys.... I bought an HTC touch pro 2 around december. As far as i can tell it has manila 2.0.... so I need to update that if I understand all the forums correctly.... my questions are... I have found a small chunk of stuff I like... (http://forum.ppcgeeks.com/showthread.php?t=100758) (I want allof this stuff expcept for his clock, can I find another clock for manila 2.1 and install it??) how do I put it together/intall it... and do I need all of it or are there parts that are redundant.
I know this is a lot of questions and for many of you I am going to look like a noob but, if i don't ask I won't learn... explanations are welcome to what every part does... I am a computer Hardware specialist so when it comes to software I struggle a bit with the different languages.
Thanks,
Timmi
P.S. I have "MightyROM_RhodiumW_021010.exe" for what I believe is the rom for manila sense 2.1. how do I load that to my phone and is that needed for the above stated mod?
