Who told you this? Of course you can use elevation data in geocentric 
mode ...
Simply use -t for imagery and -d for digitial elevation data

They are referenced, but in a non-supported coordinate frame. I never 
had problems of this kind yet.
But there are definitively geo-referenced data-sets on USGS, as I'm 
using them myself.
Use LandSAT imagery, which is WGS84 projected, so there should no 
problems here.
If you need some sample data I can share a small set on googledrive etc.

Yes it seems there is no valid projection. But still the data is

Without having your data, this is hard to tell
