Will installing any of the ROMs mess my phone up if I already have things installed?

I had it flashed to metropcs..then had juicy5 flashed..then had net/mms set up.. I no I can flash a new rom and not lose the metro pcs flash (wich technacly isnt a flash I believe thats just the term its been being called if I understand correctly)..was just hoping I could flash a new rom and not lose net/mms as they are easy to reset but just a pain lol.. was wanting to try mighty mike or juicy6 rom as juicy5 the ringtones dont work (which isnt a big deal as I dont change em much just have to change the resitry of the default ringtone to make what u want work)
