1) Usually wireless cards aren't that expensive. The hardest bit will probably be doing your homework on which makers use which chipsets. One of the frustrating things about wireless cards is that the manufacturers frequently use whatever chipset is cheap that week, and may not bother to change the model number of the card.
2)Since this is a laptop, then there is a good chance the thing is soldered to the motherboard. In that case, you'll probably need to look for a USB based wireless card. Again, you're going to want to do some research in to the specific brands/models as USB wireless sticks can present their own unique challenges. Even if it isn't soldered to the motherboard, you'll have to look at the form factor it uses. That will probably cut down on your options significantly.
