Just my opinion, but I'd strongly consider using MSD 50 lb injector's. I've used both 009's & the MSD 50's when I had my TE44 & the 50's performed MUCH better!!!
With the price difference, I would just go ahead and get the 50's or 60's. This way you should only have to buy once. You can upgrade again later and not have to worry about the injectors.
I didn't see enough noticable difference in fuel mileage to talk about when I switched from 009's to MSD 50's.....but my car definetly idled smoother and ran alot better @ wot w/ the 50's.
I would get the 50s or 60s as well. I am doing 50s on my TTA with a GT32. The 50s and 60s have better resale too. Just in case you upgrade again later.
