I've just bought a secondhand engine off eBay - what would you suggest needs replacing?

I have just purchased a secondhand Citroen C5 engine from eBay with 73,000 miles on the clock. Apart from a new cambelt, would you recommend anything else needs replacing at this stage?
Waterpump, tensioner and alternator belt. Good idea also to take the sump pan off and check the sump oil strainer because if that's clogged up with sludge the engine won't last long.
