When you go to rent the snowboard stuff, they're gonna ask your basic stats; height, weight, shoe size etc. Its important that you know these as close as possible, because the size of the snowboard you get depends on height and shoe size. And the release mechanisms on the bindings (so the snowboard releases during a fall) are based on weight.
The list of clothes and items you have looks pretty good. The only suggestion I may make would be the thermal underwear. While it keeps you nice and warm, they tend to get wet and hold water (unless of course you buy waterproof stuff). This could cause a problem during snowboarding if you wipe out a few times. If you can't find stuff that's water proof you could consider cold weather under armor or cold weather nike gear. They are a little pricey though, running about $50 apiece.
For snowboarding deals I'd suggest checking the local papers once you get there, or the website of the snow hill. My local snow hill has deals both on the web and in the paper. And if you have a big enough group, you may be able to get group discounts.

The type of gloves you should buy depends on the snow hill and lifts. If the snow hill has a lot of tow rope lifts, buy thick gloves not the little thin cloth ones. Tow rope lifts are the one where you hold onto a rope and are pulled up the hill. Usually these are for smaller ski hills that have smaller hills. The reason you would need thick gloves is because tow ropes will wear through the material of a thinner glove pretty quickly. If the hill has only chair lifts, where you sit and ride up the hills, then the glove type doesn't matter.
