Yeah, the blower would be nice, but I don't think 50 hp or so is worth the money (IMHO), but I might be overestimating how much the kit costs. However, you might consider regearing. Kind of expensive labor-wise, and not really something to take a shot at if you don't know what you're doing (you might, I sure don't).
How about a custom exhaust? About a 2.5" pipe, maybe 2.75", build it with some mandrel bend parts. I think you can order them if your shop doesn't have access. Hard to find a shop that can do them on site. Go with that Powervault, they say it's a noticeable improvement.
Do you have an intake of some sort? I have the Injen I use sometimes (not in the Summer). It sucks engine air since I don't have a divider, but at speed when outside air is blowing in, it does make a nice difference.
Find some weight to drop. Do you need that back seat? LOL!
