As of now, Rozovian has a guide (which is WiP), and needs feedback. I haven't seen it, but I am sure that it could help.
You sound like you've reached a point that I've been at since the beginning (and still am at... )
I noticed that you have questions on effects. The "mix chain" as you referred to is pretty simple. I don't know if there is a rule of thumb, but however you feel it should be ordered. If you want your delay effect to be echoed into the reverb, then go ahead. If you want to compress before you EQ, go ahead. It's up to you.
... Personally, that wouldn't really help me, but if you find some help in that, then good luck with your work
