I was fairly precautionary when I did mine, but there is a limit to just how much maintenance I felt was required.
You should be able to tell the dealer it's from a GA70 Supra from pre-88, as yellow injector plugs is a Gen2 engine. I wouldn't really be getting anything from a dealer I didn't have to though, and for me that'd only be the cam cover gaskets.
I personally wouldn't touch the inlet or exhaust gaskets unless there is currently a problem with them. Cam cover seals are $50 each trade. Seals for the timing cover I just made from squished vacuum hose, not that they actually seal anything.
I changed the oil pump seal, the front and rear main seals, the cam seals and eventually the waterpump (although I think the non-existent gasket was the problem there. Just remove these oil seals and take them to a bearing place and match them up. If they're original, they'll be made by NOK and have their part #'s on them. Same seals will cost you about 4 times as much from dealership.
Hope that helps dude.
