A couple of pointers: 1) You should be able to set (or modify) the material either on ASSET_COMPLETE or RESOURCE_COMPLETE. So there you should be able to set the mipmap property. Currently some parsers have the problem that they return a mesh (via ASSET_COMPLETE) even before it's material has been finalized. If that's the case with OBJParser (I can't remember right now) then there might be a problem with doing it on ASSET_COMPLETE, but you should be able to do it on RESOURCE_COMPLETE.
2) UV coordinates are relative, so as long as you're not changing the crop box of the texture, you can change it's dimensions all you want and it will still work. Just try it. Use "Resize Image" (not "Resize Canvas") in Photoshop and scale it up to 1024x1024 (or preferably something smaller like 512x512 for the sake of saving memory.) You'll see that there is no visible difference once mapped to a 3D object.
