I dont know how well thought out of a plan that is, but it's what i'm going to try.
**crossing fingers**
I *do* know that the store wont generate much income on its own unless you do alot of work to promote it (refine keywords in store header, etc for SEO - search engine optimization, and so forth)
i'm sure some of the more successful sellers will be in to give some good advice

edit to add - most of advice i've seen (and it makes sense) is to put slower moving items in store and faster selling items in auction/bin listings.
