Hi Mike,
Fallen behind? I have that feeling every year ;-) Everytime i master one objective a new one is born and í have to start firing up to keep up.
If you don't mind the extra time and money for upgrading i'd say go for 70-536. This is for .Net 2.0 and will give you a very strong base certification. After that go for the upgrade. If you do mind the extra time and money go straight for .net 4.0.
I'd personally have to say that although not easy 70-536 gave me a very good insight and foundation.
