The card I've got is the slightly older PC 5220. There are detailed setup 
instructions at http://www.ka9q.net/5220.html
Everything works with the stock kernels. 
The current 5740 cards are supposed to work exactly the same way just with 
different product id. Put the card in, run lspci -vv and pull the ID out and 
you're set.

Yes, usually no problem... After all, they use the same controller chips as 
any laptop does. I've bought several random ones off of ebay without issues - 
but if you want to make 100% sure go for a Elan card - 
http://www.elandigitalsystems.com/adapter/p111.php - they have specific 
instructions for using their cards with linux on their webpage. 

From everything I can tell, the card is less of an issue than your motherboard 
bios, especially with power management. As a bridge chip it requires special 
treatment... So if you have issues with the pcmcia card, try without acpi or 
with a pci irq routing.
