That's a lot of Patagonia and Montbell for a student budget.
I think that is too many layers for up top. You'll want a baselayer, a warmer midlayer (fleece), a hardshell, and a warm jacket. The windshirt and softshell are a bit redundant. I would go with:
1) Whatever zip neck midweight baselayer you can find on sale
2) Any lightweight fleece (think 100 wt or R1, etc). You can get these at thrift stores, Marshalls, TJMax, etc. Add a thick powerstretch balaclava and you have something cheaper and more versatile than an r1 hoody.
3) The First Ascent hardshells are a great value and always on sale. Try it on with your helmet.
4) Down jackets are also expensive. This is where I would spend most of my money (they last forever). The UL Down will not be warm enough unless the weather is just awesome. The Alpine Light is nice.
A windshirt is nice if your hardshell is not breathable and the weather isn't too bad. Softshells are comfy, but too heavy for what you get.
Pant layering is easy. Light softshell pants that cut the wind just a little, midweight baselayer, and a hardshell pant. It's nice to have full zips for the hardshell pants, but not necessary.
The main thing that matters for boots is fit, so you're just going to have to try on every pair you can find. You can usually score used plastics on craigslist for next to nothing. Definitely get something insulated if you have cold feet.
