I'll try to answer these for you.
1; Any good grade of 10w-30 will be fine. There are some who will say you need to use "special" oil for older engines due to the lower ZDDP levels in modern oils, but that really doesn't apply to stock engines that are broken in. That said, however, if you are concerned about the ZDDP levels, and want something that has a higher amount, Valvoline and Valvoline VR-1 have the highest amount (I use VR-1 in mine).
2; Go with what the shop manual says to use.
3: I really can't help you much on this one, as I am running a different filter unit on mine. However, I do know that the cartiges for the Fram version are readily available. If the decals are still legible on the canister, it should tell you which filter it takes, and you can cross reference from there. some may look different, but fitment shouldn't be an issue.
4: Any modern chassis lubricant will be fine, either regular or synthetic.
5: same as 4, just make sure that it is a semi fluid grease.
6:Agine, go with the manual. You will have to be specific when you get the lube, as many modern "gear lubes" are not the correct spec for the older transmission. You want to stay away from GL-5.
7; Again, modern coolants will be fine, the "mix with any" type is the one you want. Do not use Dex-Cool (pink in color). A 50-50 mix is best. It is also available in a premix if you do not want to mix it youself, but it is a little more expensive.
8; Premium in these engines would be wasting money, and is not necessary. Regular 87 octane will be fine. Unless you're going to work the engine hard, a lead substitute reall isn't necessary, and if the engine has been rebuilt, there's a good chance it has hardened seat installed.
