If you are bent on moving ahead with tube experimenting and you're a fundamentally happy with your unit as it is just try changing the smallest/cheapest tube first. The power tubes will usually effect a larger change, but are more expensive and involved. And, even if you find different ones you like, you will probably try to fine tune the sound by changing the small tubes.
I don't know your amp, but there are a lot of good 12AX's that are relatively inexpensive. Not so much with the 6SN7's.
But I agree with others, relax and enjoy for a while before you start changing tubes.
