Help me interpret compression/leakdown!

My car started running very rough last tuesday. I took it to a good indy and they did a compression and leakdown test. Could somebody help me interpret the results?

Compression test: # 1-210 #2-95 #3-170 #4-225
Leakdown Test: #2-90% Leak-intake valve

The shop wants to do a valve job on the head, but I want to be as sure as possible there is nothing else wrong with the engine before I give them the Ok. Are these results enough to be reasonably sure I don't have lower end work in my future?

cheers,
dan r.

EDIT: Car has 174k miles, original head, replaced timing chain and tensioner at 90k
