You're going to get a ton of different opinions here, but I think with the blower you really have all the power you need. You can go to a smaller pulley and make more boost. Once your cam goes in it will drop your boost anyway so you'll need it.
I went with a Comp VVT cam because I really just wanted the sound. An LS3 conversion is more expensive as well, but if you're doing your own labor you'll save a bunch.
If I hadn't gone with a blower I would've gone with a larger cam and an LS3 conversion.
Just my opinion...since you have the blower already...go with a VVT cam (and a torque converter).
