Concentrate on making your main blog the best you can first. Fill it with text rich posts, optimize the hell out of your side bars, etc.

And I have to tell you hon, if you're still asking these questions you have not read enough here yet. Go to the tutorials and read that shit until your eyes bleed. Then take a break. Print it out and carry the damn thing around with you. Keep reading until you understand it. Because the answers to a lot of your questions can be found either in the tutorials forum or in the stickies at the top of each forum.

As for feeder vs quality blogs....create feeder blogs when you are too damn lazy to do anything on your main blog(s) but feel the need to be productive. I go on feeder binges where my brain is too tired to really do something awesome but I want to do something that adds to my network and my overall success.

Feeder blogs are not necessary. They are what you do once you know that your main blog(s) is the best you can make it.
