Hi Chucky,
You might find this map of the Eta Carinae nebula helpful
http://www.atlasoftheuniverse.com/nebulae/ngc3372.html
You will need to bear in mind that the image extends well beyond NGC 3372 itself. AS Sab said, you're probably looking at Tr 14 + 16 and Collinder 228. You would probably see the nebula as far as Bochum 10 and a little beyond then see NGCs 3324 and 3293 as separate entities to 3372 - 3324 as a nebulosity with some stars in it and 3293 as a discrete and beautiful cluster.
It's a fascinating area. The most useful map of it that I've found so far is in the Night Sky Observer's Guide - mainly because it's based on a B & W image that's pretty much like the view through the eyepiece.
Hope this helps.
