GTK+ warnings aren't uncommon, as GTK+ behaviour gradually changes over
time and programs don't always keep up.  If the program operates
correctly, and upstream says they can be ignored, then I wouldn't worry
about them.

As for choosing between GTK+ 2 vs 3, I would go with the upstream
default.

A D-Bus session daemon is required for most modern desktop software
nowadays, so I wouldn't consider this a setback.
