As those are non drive side spokes, you can just straighten them and reuse them. That will make your learning experience even cheaper!
Can the spoke nipples be turned easily? Often old wheels don't come apart with much ease because the nipples can stick. But usually you can get them to turn by heating them a little with a torch.
