I've gone ahead and ordered the long block, my next question is:

Would I be able to use my 1965 289 28 oz imbalance on my new
1968 302 (rebuilt to oe specs) engine?

As far as I know, I should be able to, but I just want to make sure that I get the right parts before I go and kill my engine

All 289 parts will fit on your '68 spec 302 engine. Here's some misc information:

a. if you decide to use T5 or Tremec 3550 transmission, then the pilot bearing in the back of the crank must be the 5.0L needle bearing model.

b. if your engine is an overbore (most highly), plan to bump your radiator at least one row of cores to account for the heavier heat burden. If you also run air conditioning, a four core is a good idea. Three core will work with all your present parts (fan, spacer) except the fan shroud brackets and for this you'll need the three core part. Four core may require the fan spacer to be trimmed or replaced as well as having different shroud brackets.

c. Advise using FlowKooler aluminum replacement for cast iron water pump as this model has 35% better flow characteristics below 3000 rpm which is where you're likely to be most of the time. Summit Racing has these, about $70.

If you use an aftermarket intake manifold and the upper radiator hose doesn't fit too well, try the hose for a '64 Ford Galaxie 289. It's curvature is a bit tighter than Mustangs and it fit great on my 5.0L with Weiand Stealth whereas the OEM part fit like doo-doo.

Good luck and take your time with the retrofit. If something doesn't seem to fit, don't force it...usually there's a reason why.
