I need to replace my crank. The bike has a Sora drivetrain. Can I use Shimano 9spd cranks?(i.e. 105/ultegra...)

You have to change the tapered spindle BB to the splined spindle to match the 105 and better cranks.

How would the 8spd chain perform on the 9spd cranks?

Not really an issue,or just use a 9 speed chain.
