10.99/lb for Cascades? You won the lottery! Where did you get them?

For an IPA, I'd hop like this...
60 min - 2 oz
20 min - 1 oz
10 min - 1 oz
0 min - 1 oz
dry hop - 1 or 2 oz
With this, you'll definitely know whether you like cascades or not.

For an APA, drop the 60 and dry hop to 1 oz and leave out the 10 min addition.

For dry hopping, it is paramount to get the hops in contact with the beer. Use a hop bag and weigh it down with some washers or marbles until it just sinks below the surface but doesn't 'thunk' on the bottom of the fermenter. Sanitize the bag and weights of course.

There's a lot of good advice on this site for dry hopping.
