I'd just listen and enjoy. It will tell you if it needs attention.
I had the same situation come up a couple of years ago with a vintage Sony PS-X50 turntable. I always wanted one and found one at a reasonable price. So, do I dump some money into refreshing it or just re-cartridge it and listen for awhile and then decide? I put on the tried and true 2M Blue. Two years later I'm still loving it as is. I don't feel any need to do anything else to it (other than polish the lid,, what is this lens restorer you speak of, must look into).
