OMG you're already on pg. 10?! You're one popular guy Scott.
Ok so congrats on the A!
Wooohoooo!! You haven't cancelled Boma. You definately need to try it, it was GUD as Buzz says.
I think I pretty much answered your IOA/US questions on my TR, but I'll say some more here.
I know Disney has a service with MEARS, but I think you have to pay and like someone else said you have to arrange pick up to go and come back.
You guys can definately get both parks done especially in September, not too busy. I went in Sept. in '05 and almost all rides at IoA were walk ons, the worst waits were Spidy and Hulk. I haven't been to US in Sept, but it's usually less busier than IoA.
Definately start at IoA though as there's more to ride and I
know you'll be taking pictures like crazy over there so plan for that.
Also IMO Universal has better food than IoA, although the restaurant by the Jurassic Park ride is pretty good; but I'd still do US food.
Universal has more shows than anything so plan a little for that. The Express pass might actually come in more handy there than at IoA and I'm pretty sure US closes a little later than IoA which closes at 6pm.
