I think most do make a starter to "wake up" the yeast and get them prepared for the battle ahead.

How long ago was the harvest?

MrMalty would say that if it's been sitting a while that a starter isn't optional.

This depends on alot of things like:

1. Age of yeast.
2. OG of wort.
3. Volume of brew.

Numerous other parameters affect fermentation but those are the basics, no way to calculate without knowing this.
You can try mrmalty to calculate it here: http://www.mrmalty.com/calc/calc.html

I think 4 oz of high alpha hops for 60 minutes is too much. I'd (at least) half that first hop addition, then take the 2 oz you saved and throw them in at flame out.. A recent basicbrewing pod cast seemed to come to the conclusion that you can't detect IBUs above about 60 anyway.
Here's a great article about late hop additions: http://www.mrmalty.com/late_hopping.php

I would say no starter and two of those jars if you're two weeks old.

I look forward to hearing more on this topic.

My initial reaction it to use Mr. Malty with the slurry option. That will base the pitching rate on a variety of your beer needs.

My vote is h=just do the starter if it is 2 weeks old ...you have plenty of good looking yeast -- let's make sure they have their game on.
