The simplest is probably to wrap the call to Needs in Block, like this:

Block[{$ContextPath = $ContextPath}, Needs["Combinatorica`"]]

The net effect is that the value of $ContextPath is not modified globally while
Combinatorica` loads all right. You can then use the full names for its
functions
as you suggested.

Leonid
