If i'm trying to get to XµF value would I just put 2 caps in line that add up to XµF value?
Also, what type of caps do I need? I assume: Axial-Lead, but do they need to be electrolytic or non polarized?

To add caps you have to put them in parrellel...like connect the two leads on one end and the two leads on the other end and use it like one big fat cap. Not like resistors were you can have them is series and it just adds up.
Im not really sure what the exact difference is between electrolytic and non polar, I would guess they don't really affect each other. Like elctrolytic is what it's made up of and polarized is how it can be connected.
If you use electrolytics in a crossover, make sure that they're non-polar, or if they're polar, that they're connected back-to-back in series (i.e., + to + or - to -). mikee's formulas are correct.
I guess the other thing is only use electros if you can't afford Metalised polypropylene (or better) caps (or can't physically construct a big enough value from them).
The metalised polypropylene are supposed to be much better sonically than electros (and based on some cheap crossovers I have owned which used electros, compared to more expensive xovers I have which use polypropylene for all but the biggest cap, I would have to say I agree with the claim).
