I predict you'll be happy with your purchase. I bought the same machine a few years ago.
Just a couple of quick suggestions...
First, be sure to secure it to floor if you're able to. I found the machine to be quite "tippy" until I bolted it to the concrete floor in my shop.
Second, I see you got a vise with a swivel base... You'll probably want to use the vise without the base most of the time. A couple of inches in Z, and the extra rigidity are more than offset the hassle with remounting it if you ever need to rotate the vise (I've not used mine once in 3 years)...
If you can swing it, the powered X-axis kit that Grizzly sells saves a lot of hand-cranking.
I just recently built a mist-cooler for mine - best upgrade ever! I'm now routinely taking cuts that are twice as heavy as I was taking previously and the cutter stays cold and sharper longer (chips are hot, but the cutter and the workpiece stay cool).
