GFCI on ungrounded outlet circuit

Planning on adding a GFCI outlet to all ungrounded outlet circuits. Circuits are 12/2 with 20 AMP breaker, do I have to use 20 AMP GFCI outlet or can a 15 AMP GFCI outlet be used?

Also can all additional outlets after GFCI (connected to load) be changed to 3 prong?

15 amp can be used.

Not clear what your next question is. Of course you can install new 3 prong outlets, but of course they won't be grounded. Since they will be GFCI protected and not grounded, they should have a sticker on them that says (drumroll please....) "GFCI protected, not grounded". GFCI outlets normally come with a few stickers for the GFCI outlets and downstream load outlets. (The initial GFCI outlet should be marked with a "no ground" sticker too, of course.)
