My second question is, since I have the pan off should I clean out the oil pump? Is it a tough task? Anything I should know?
Thanks

Most pumps will have some scoring on the gears but that is okay. The thing to watch for is loosness in the main shaft.
I also like to look at the relief valve spring, they can have a fair amount of wear on them from rubbing against the housing.
New pumps are available, even on ebay.
