Answer 1

Find out what calc your math profs use. So they can help you learn how to use it

I really like my TI 89, it's not too big but it still does the reductions and pretty print.

Answer 2

If you will be taking calculus soon, then the TI-89 is the best trade off of value and functionality.  It does a lot of calculus operations (differentiation, summation, limits, integration, etc), has great graphing capabilities (polar, rectangular, 3D, etc.).  Unlike its big brother the Voyage, it has a standard form factor, meaning it is less likely to be prohibited from tests.  It has almost all of the functionality of the Voyage but at a much better price point.  It is the best for the cost out of what you listed.
