No big deal, there...
You can play with just a PH and MM. Heck, I ran with just the 3E PH and the limited selection in the back of the PH (early 3E PH's had a monsters and GM section, very limited, for converting early, and a set of conversion guidelines in a booklet.). I got the MM, and then the DMG.
I never did bother with a 3/3.5 DM's guide. I found it needless. The core rules are all in the Players handbook, and anything else you need you can sort of create from there.
