Alignment? Probably yes but I wouldn't worry about that right now.

At this stage I would take out the upright and use a press to get it out. I have a small cheap press ($120) that has paid for itself 10 times over. Can you get access to one?
Lots of PB Blaster or make your own using ATF and acetone (50/50) would be very helpful.

The trick with stuff like this is to hit it in the right place. A twisting force can work wonders.
