Congrats on getting after it Mike! I know you've been excited about this for a long time.
Best advice I can give you is to grab a can of PB Blaster the next time you're at the parts store (even some Dollar Generals carry it). Spray a little bit, take a beer / sauna break, and by the time you get back you can break them loose. It's so good it even works uphill.
Try it. :-D
