If you have 24lb injectors you should be fine.

It should run fine. Plenty of guys build that combo. A tune might wring out a few more hp, but not 100% necessary

Should be OK, I had that setup on my 89 for a while (24's with a TF1) an it didn't idle great, but I was able to drive it until I got a Tweecer.
