In SU,
As suggested already
But: Add this -difficult to find these days- ruby.

This will remove inner faces (non manifolds).
Very important because:
In blender:
-Import the obj
-edit mode (TAB), [W] menu, remove doubles! This will weld all overlapping vertices automatically.
-Hit [ctrl+N], it's the shortcut for fixing normals. (it will be a mess if non manifolds/inner faces exist!)
SU UVs are still there and you may edit them in UV editor.
TIGs obj exporter is an excellent tool!
If you love blender (you should lol) and its new render engine (cycles), it's possible to model in SU only and just import.
Some important things to know about blender.
-You may wish to re scale SU imported objects. In this case after scale/rotation or other transformations, hit [ctrl+A], this brings up a menu, apply these data transformations. Now, bumps/displacements etc will work correctly.
(blender avoids to do this automatically for a good reason, it has to do with its particles/instancing system)
-you may face depth clipping in 3d view port. Under N panel / view, clip start-end, here your solution
-I suppose, you already edited the default preferences of blender, making it similar to SU.
-You already learned the shortcuts of transformations, yes?
[G] for move-grab, [G]+[x or y or z] for direction, [G]+[shift+z] for moving in xy plane, etc etc , yes? 😉
You also learned how to use the excellent snapping methods of blender. If not, ask me. 😆
