1. Table saws are good, very useful and you have selected a reasonable price point. Remember that carbide blades will cut aluminum with great care.
2. I have no recommendations for you at that price range really, I have heard good things about the X-carve and shapeco and those should be in the range you need. One of them 2 has full cad of the machine free to download so you could get the minimum and beef it up and/or make another with the first.
3. A nice arbor press in that range will be around 400-700, plus 200 for the broach. The cost of entry sucks but a good arbor press is a very useful tool for FRC teams even more so when paired with a lathe and mill.
4. The Harbor Freight one will be enough to start you, I have a few upgrades to suggest.
Buy some digital scales for the X and Y axis (and your mill)

I would suggest a set of
cutters like this as well
5. Harbor freight has a 1 inch belt sander for around $50, not fantastic but it helps.

All those sites have good stuff for cheap, let me know if there is anything in particular you are still looking for.
EDIT: Chris is me has a good point about the lathe
