You can check out Camp5, they are in various locations now not just 1U. Will give you basic ropes course and techniques needed to climb safely.

In terms of equipment yes of course you will need a lot of equipment (ropes, harness, shoes, chalk bag, belay device etc) which means I would recommend you join a climbing tour so they will provide all the stuff you need for a fee rather than you buying it all since you have not climbed before.
