hehe, just an observation, but you have 3 rams listed in your sig =P
Timster - Rams are the coolest fish I have ever kept, I always recommend them whenever I get the chance. In a 30 gallon I would recommend 1 male and 2 or 3 females. The thing to watch out for with rams is your water quality. I do weekly 25% water changes myself.
I've kept blue gouramis as well, but not WITH rams. I imagine you'll see small skirmishes over territory, possibly, but as a gourami tends to hang out up top, and a ram tends to hang around the bottom, it should be fine. I've never kept barbs and the little I've heard about them is that the normal "tiger" color morph can tend to be a fin-nipper, while the "green" morph tends to be calmer and less mischevious.
I'd say you're on the right track though, and you could even add some other species as well, some type of scavenger like corys or the like, maybe 2 or 3 dwarf gouramis, or whatever you like
