You have a very small room, with very high ceilings. You will seat 100 or less, and have no need of portability. You want to be able to put cds through the PA, as well as pump vocals and keys, and when the band is loud, guitars, bass, and drums through the PA. I stress again, portability is not a concern, and on some occasions, you will need to run a band through the PA to keep the room mix working, so nothing specifically gets buried. You might prefer to buy in phases... like start with mains, then subs, then yadda yadda. You don't want to break the bank, but you will pay what you have to, in order to make the mix passable. What do you buy?
