It would be good for you to sit down with an experienced mixer and ask a lot of questions. Maybe you can find some demo sessions online and study the signal path.

Here is a good book:

I would say don't put any plugs in the chain until you hear a reason for needing them. Experience will tell you when you need them.

Good luck
