Looking For ROMS!

Hello, I'm a self taught techie currently exploring the world of custom ROMS. Only by accident did I really have to start using custom ROMS but now I rather enjoy them. Unfortunately I can't, for life of me, find a really nice ROM for my Galaxy Tab 4 7.0 (t230nu). Can you guys provide me with some good suggestions? Also I installed the Prism Barebones ROM and I like the speed that I have with it but unfortunately I lost a lot of my graphics for the games that I play. Can anyone provide any suggestions? Then on a side note, I'm looking for a rooting method for the new update to the LG G Vista for android 5.1.1 I've been keeping an eye out for anything and have yet to see a single thing. Suggestions and links would be greatly appreciated, also really interested in learning programming for some Android software if anyone has any good suggestions for a beginner.
