I would suggest reading the installation guide. Then reading it again, and one more time. That is not meant to be an obnoxious answer, but when I was trying to decide which saw to get, I got a soft copy of the manual, printed and read it. By the time I got the saw, I was quite comfortable with the assembly.
Mine went quite well, and no significant problems. What problems there were came about when trying to install the cast iron table tops. I thought it was a good idea to them on the floor and tighten everything down without trying to balance the tops! It worked VERY well, Then I had to get the saw right side up! Managed to do it, but it was a struggle and I kept having visions of the metal sides bending. Didn't happen, but I was nervous! I had very little adjustment to make with my blade and fence. It essentially went together square. Probably if I had not have read all of the stuff on adjusting the saw, I would never have even checked it!
Congratulations on the great price! When I got mine, it was listed at $599, on sale for $549. I asked if they would take $500 for it, and they agreed. Kicker - they were offering a $100 gift card on all purchases greater than $499! Told myself I really got it for $400 because of the savings! Yours was a great deal!
