How to install exterior door ahead of vinyl siding

So I am getting my house resided with vinyl in three weeks. I've taken it upon myself to install the new doors before the installers arrive. So my question is what's the proper way to water proof the opening before the vinyl?

My plan was to wrap the opening in tyvek and tape it to the existing felt paper. The felt paper will be removed and the house will be wrapped in tyvek during the vinyl install. I just don't want to cause more work for the installers.

Your plan should not be a problem for installers.

Bottom of the opening needs to be flashed.
Under the threshold on the outside wall needs to be fully supported.
I use a piece of 1 X 4 or 6" PVC lumber.
