Chris Church currently has a great deal on mics and power options right now... I'd definitely look at those. Cheap mics = cheap sound. Even those his mics are pretty inexpensive, they rival many of the other similar mics that are more expensive. I've owned AT933's, CA-14 omnis and cards, DPA 4061 (omnis), Countryman B3 (omnis) and AT853 cards. I personally prefer the sound of the AT853's, however, they're pretty hard to come by so if I didn't have the option of getting those, I'd grab the CA-14 cards (or omnis) depending on where you'll be standing/setting up for shows.
Battery box is probably fine -- I think preamps are overkill for most loud rock shows but they do have their place for pop shows/jazz/classical/etc.
I'm not a huge fan of Sound Professionals products - I think they're overpriced for what they are. Chris is saying that all orders before the end of today will ship by mid-February and I'm sure the 6 week wait will be worth it.
