My hop self-education came from a season of brewing session ales (not too strong, not too bitter, easy to drink mass quantities without getting too stupid), each with identical ingredients (8# pale with 8oz crystal I think?) with exception of the hops.
They had a starting gravity in the 1.040 range, and the hop regimen was 1oz for 60, .5 for 30, .25 for 15, and .25 at flameout ( I think? again going by memory). This gave a good indication of bitterness, flavor and aroma without being overpowering.
Four ounces per batch sounds like a lot, and it sounds expensive if you're not buying them in bulk (hopsdirect dot com, by the pound for under twenty bucks, heck yeah!).
