Oh boy... O.k....
The water pump is mounted just inside the front of the engine, on the engine block, and if it leaks, yes, you will find low coolant, and water/coolant in your oil - milk shake on the dipstick, foaming, sludge, etc. Valve stem seals are up on the top of both sides of the engine on top the cylinder heads, under the valve covers (and under some other odds and ends, like cams, rockers, springs, etc).
The two things have nothing to do with each other, besides oil.
The valve stem seals wear with time on the engine, and seem to be kinda problematic on the 2.7. The water pump will wear with time, but at a separate interval. The water pump isn't for the novice to change, but it is easier than the valve stem seals IMO. BUT - both jobs are well with-in the grasp of the home mechanic who has some time under his belt, and some tools in the tool box... AND having an account here helps.
I'm not on my own PC here, so it isn't terribly easy for me to find illustrations - but if you need any more help with what that means that I wrote above, let me know - we'll get you some pictures.
