How many miles can you get out of a chain and sprockets?

I'm definitely going to replace the sprockets with the chain. I think I want to go 14 front because the rear of the 620s is a 48 and I can't find anything larger for the back. Are there name brand sprockets or a style that I should be looking for?

Update:

I got a new chain and sprockets from Candice at CA-cycleworks and she was great! Very helpful and I got my parts quick.

I'm just about to put the chain back on. I planned on removing and installing in one day and then once the wheel and chain were off I had to clean EVERYTHING. That always happens to me.

I had a question about the master link, I got the EK screw type master since I don't have a chain tool. Can I have the side that snaps off facing the wheel? If you don't have experience with the screw type master can you have a rivet master with the pressed side of the pins facing the wheel?

If I do that I have to push the current pin out from the non wheel side correct?
