Before you go through any expense I would first check with your local authorities to see if using the well is even allowed.
If allowed, At a minimum your will need a complete separate plumbing system for the applications that will use the well. You will probably be required to also fit your home with a backflow prevention device to prevent any possible contamination of the public water supply by water from your well in the event it did somehow mix with your homes water supply.
Then comes finding out what it takes to make the well work again.
I'm sure Speedbump will be along to help you out with what you need to know about pumps.
