Will the Tamron 90mm f/2.8 macro lens I have work with the F4 body that I have coming?

It's a screw driven AF lens, therefore AF will work with your F4; but I'm not too sure whether the F4 will be able to utilize the distance info your Tamron is able to provide for the calculation of flash metering.

If it has an aperture ring it would work whether or not it has built in motor or uses the screw driver. If it doesn't have an aperture ring then it only work in S and P mode.

The TTL flash circuitry on the F4 is a bit primitive, compared to the F5 and other later AF Nikons. So, it will treat it like a normal AF lens.
Only thing that matters with an F4 is that the lens have an aperture ring, since there is no secondary command dial for setting apertures. In fact, on all the F5's I've owned and on my D1H, I've had the cameras set up to require usage of the aperture ring in A or M modes.
With respect to AF versus AF-I and AF-S, The F4 is able to drive all three without problems. In fact, with the AF-I and AF-S lenses, the F4 is as fast as an F5. But, it does hunt around a little more than the F5, since it only has the single-point sensor, instead of the five-point sensor of the F5, D1 series, and F100.
