Using Online Check In in Y

Am planning on a last minute weekend trek to Vegas, and due to PE being sold out, will have to travel Y [xx(]
I understand that only a certain amount of Y is available for preallocation (and not the front section?), so I assume that if you check in online at t-24hrs, you should get a full choice of decent Y seats in the front section, possibly including bulkheads if there are no brats onboard. I assume that exit seats are still off limits, due to the £50 charge.
Can anyone with experience of the process confirm or deny my assumptions? Anything else to be aware of?
Cheers
