Main jets are the jets that are used during WOT. these are the stock 98

pilot jets are the jets that are used during idle. these are the stock 38 (I think?)

Pilot jets are usually ok to keep stock, all you have to do is back the mix screws out a little. If you back the mixture screws out past like 3 turns, consider going up a size on the pilot jets.

I used the oem equivalent jets. No problems with them.
