a) if you want commentary on your space post something recorded in the space. It'll help me work out where your ears & expectations are at.
b) yep, use what you have
c) improve what you have as & when you can
d) look into the people giving you suggestions: suss out their preferences, the're reputatuions &, if possible, some of their recordings THEN decide whether or not to accept their advice.
There are people I know to ignore or know to pay attention to as well as newer/less frequent participants who seem interesting/have potential that I will track for a while until I decide whether to trust them or not.
We all have some poor stuff for a variety of reasons. The room may be one of those reasons. A bad room will have a stacked effected when tracking and an even bigger one when mixing - add those together & a good song will suffer sonically.
By the way dreib, I don't see any links to your stuff so I can't make any judgements about the room at your end. I know I get a big bass build up in my little space that increases mid mud congestion & it's the next thing I'll address when I can afford/manage it. In the meantime I'll do what I can with what I have.
