I Have Both a Steam and a Client Install

[w_attick47]

I have an install on Steam (IL-2 Sturmovik:  Battle of Stalingrad) and an install of IL-2 Sturmovik Great Battles Client in my control panel.  Do I need both or can I eliminate the Client?  I purchased BOS on Steam first.

If by Great Battles Client you mean the installation/set-up front end, no you do not need both.  If you use Steam then all updates will come onto your steam install automatically, or depending on how you have set your update options. I have it on "always keep this game up to date" and have never had a problem.
