save stock ROM and setting

[okwassup]

Never did a thing with my HTC TP1, since its the one i use to log online., bought a used one , and know have the courage to play with it., i found some files on how to fix the meid ..etc , i would like to see if i can do it ., but before that i think i would like to flash the touch pro sprint with different roms , and unlock it, iam sure there is so much to know but hope i can get the basics.
how do i save the stock rom of the touch pro i have , i seen that they have them online as original stock rom...etc , but iam sure would be best if i save what i have with all the setting for my sprint phone.

can one give me a link or guid of how its done please .
sincerely
