Will someone be so kind as to point me in the direction of an answer for, “I have him grappled, can I damage him with no weapon? Do I need to attack?”
Thanks,
EJ
Anyone can punch someone: see Fist on weapon table Core Rulebook pg. 278. So no weapon is needed.
As to an attack, yes you need to attack/strike: all grapple does is give the Grabbed or Restrained conditions and only requires a single hand so you can use any one handed weapon or unarmed attack you happen to have. Note though that grapple is an attack, so any attacks after that have a multiple attack penalty.
PS: Monks and barbarians have feats that deal damage when you grapple someone as part of the grapple.

Unlike PF1 you don't get to freely damage someone for having them grappled.
And unless you critically succeed on a grapple check, you've only imposed the grabbed condition, which causes immobilized and flat-footed. Unless what you're after specifically is immobilized, usually grappling isn't great. The good news is that it basically requires (or allows) no investment.
