Most shops would likely charge 3-400 bucks for labor. I can't see this taking more than a few hours.
I'd say you're spot on @

Be prepared to give some attention to your flywheel, it may need resurfacing or replacement. It's likely you've got some hot spots.
There could also be other things amiss that caused your clutch to fail early.
When I do replacements, I usually get the clutch disc, the pressure plate and a new throwout bearing.
Additionally, if you buy a kit, it comes with the throwout bearing, but I am weary of what some vendors/manufacturers supply with their kit so I get the OEM bearing unless I know the supplied one is as good or better. I've been burned a few times on relying on the supplied bearing.
Finally, if they have to remove the flywheel, you'll want to replace the bolts with new OEM bolts.
There's lot's of options, look into some local performance oriented shops.
If you're concerned about warranty then the dealer is going to rape you on the labor.
