I saw that you already ordered a wheel, but another option would have been to just buy a new rim of the same model.

Loosen all spokes, tape a new rim (same model, thus the same spoke length) to the old rim putting the inner tube valve holes together. Then transfer one spoke from the old rim to the new rim, one spoke at a time. You obviously would have to transfer spokes from one side of the hub before the spokes from the other side of the hub. Then true it up. Takes patience, I generally budget an hour to true up a new wheel after I have it laced. Transferring one spoke from rim to rim at a time is also time consuming, probably a couple hours. It is a good way to learn without the complications of learning to lace the wheel.

I assume the rear is the one that cracked. Truing up a new wheel is much better to learn the first time on an undished front wheel, but you can learn on a back if you are a bit more patient. If it is the rear, you may want to remove the cassette first if it is covered with dirty grease.

I do not have a truing stand, for decades I have use the frame and brake pads. A truing stand makes it a lot easier, but is not absolutely necessary.
