I totally agree with Son of a Coma Guy. Some great House/Wilson stuff.

Here are my suggestions:

House Training-Introduces Wilson's ex, Bonnie. We find out more about Wilson when House asks Bonnie.
Family- Some great House and Wilson scenes- especially cane shopping, oh, and the dog.
Resignation- I could be wrong but I think this is where House and Wilson drug each other.

I love Half Wit

For H/W angsty stuff:
Finding Judas
Merry Little Christmas
