Andy,

It may seem overwheliming at first, but once you get the hang of it it's very rewarding. You have BB2016, so you already have RealBand. It's a full-featured DAW with a ton of features.
Don't give up! There are a bunch of great people here who will help you, not to mention PG staff.
I have a lot of plugins, programs, etc. and I normally mix with only EQ, compression and reverb. The thing to remember is "less is more".
Have you played around with RealBand much yet? That's where I would start.

Regards,

Bob
