Yes, PG can hit any monster that does more than 2 damage.
Actual EXP (assuming level 31 PG + level 170 NL selling) @ 26 = 350000 exp (more than enough for 2 levels) so you'll end up leveling up once and then gaining 1 less than the amount of exp needed to level up again.
Toss in an 8x Priest with max HS and it goes to 400000 exp.
Goes almost linearly with level, at level 60 in the same parties you'd be getting 700,000 or 830,000 exp (still enough to level up once? Close anyway).
