At CGArena, Alexander Tomchuk has a great walkthrough of modeling a giant monster called “Ashoan” using 3ds Max and ZBrush.

No need to unwrap model before exporting to ZBrush on this stage. You can do it later. What I do, is just exporting the model without Turbo Smooth modifier on it. Then, even if you finished with sculpting, you always can export first Sub divide level to 3ds max and change what ever you need. Then import it back in ZBrush over the first subdivide level. Just remember, you can not add or remove polygons.
