I have the Tactical and it has most of what you are looking for. It has been a great gun and very reliable for me with good+ accuracy to boot. It does have the ambi safety, but you can fix that easy enough. It also has a long trigger, but doesn't have the over-travel screw.
Another thing to consider, if you are planning to throw a couple hundred more into it, look at the STI Spartan. They are a $650ish and are basically a STI tuned/tweaked Rock Island. That is probably my next upgrade.
