New User could use some advice

[BigBen19]

I am new to this whole ppc thing, so I apologize for posting what I am sure will be some redundant questions. However, I am a little in the dark regarding some of the "techier" stuff in modifying these devices. I am pretty unsatisfied with the overall layout, interface, and customization of the factory software on my HTC touch diamond. I know this is a long list of demands, but I would like mainly to have phone, texting, internet, a gyrator-type software, a better contact list and phonebook, as well as a few other things. I am hoping someone can direct me to some ROM's that are not too complex, this thing eats battery life as it is, and maybe share their experiences.

Cheers!
