I don't think they speak too much English at the rink, but I'm sure that they'll be able to sort you out.
They do rent skates, and maybe helmets, but I am not sure about sticks. At the open ice times, people normally have only skates, stick and puck. There is a store just near the rink call Chip Sport, and a small store at the rink itself that sells gear as well.
When I get their schedule, I'll post it here. September might be tough for me, but I'll let you know when I'm planning getting out there.

Cheers
