Hi,
There are many 3 axis stepper driver boards available from China (on ebay) at such low prices that it is hardly worth building your own. Some of these boards incorporate the charge pump safety circuit and spindle control relay as well as providing opto isolation of all inputs and outputs they also have provision for adding a forth axis at a later time.
Yes it is OK for limit switches to pull to ground but make sure it is the controller ground and that ground loops are not created in the process.
If you have the time to take a look at my website you can see the machine which I constructed and there are some details of the problems I encountered in the process.

I hope this helps. Good luck with your build - please post pictures of your progress.
