Very young fish can be delicate. A 2-3" individual has a better chance of surviving and acclimating. The only time to avoid collecting fish is during the heat of summer; the fish may be stressed out from low oxygen levels and be more likely to die or get infected.
Pumpkinseeds can be kept with many other fish, including other mid-sized sunfish, perch, smaller catfish, as well as moderate to large minnows and darters. Sunfish are aggressive feeders, so you may need to take extra steps at feeding time to be sure less aggressive fish such as darters or pickerel get enough to eat.
