I don't believe you can change the sliders online... we need to wait for a tuning option for that.
You will need to be on the same console to do a co-op season.
It is fairly simple to get you both on an EASHL team. You can either create your own(if you want it to be just the two of you), or you can join one. There is an
extension of OS based on the EASHL. You will find people discussing NHL 11, as well as a recruiting section for you guys.
The best way to play on a team online would be to play an OTP game. However, if you are on the same console, you can play together without restrictions by position.
I hope this helps!
