I would agree with Edi and recommend TIFF. It's easy to move around and 
deal with, and is the fastest of the raster formats. (unless something 
new has come up?)

I would also agree with Mark: a tileindex is for mosaicing many TIFFs, 
and if your result is 1 single TIFF the tileindex is unnecessary.

Edi's recommendation about a "internal tile" is VERY important. It costs 
slightly more disk space, but makes a tremendous improvement in the 
random access within the TIFF's extent. The overviews accomplish a 
similar performance gain, but for views in which the TIFF's extent is 
only a subset of what's showing on the map.
