New User could use some advice

[BigBen19]

I have looked at this, but some ROM's seem to lack, at least to me, maybe not experienced users, a list of what applications are included. Also, the screen shots are helpful in selecting a better interface and some lack these. I will continue to read those threads though. By trial and error do you mean that I can easily upload and ROM and replace it once I have installed it on my device if I don't like it?

Thanks, any help is appreciated.
