Need advice before servicing Ultegra 10-spd hubs

I've got a used (but very low miles) wheelset on the way, built with FH-6600 Ultegra hubs, and I'd like to inspect, re-grease, and adjust the internals, before putting them into use. The wheels come from a private ebay seller, who is bike guy, very knowledgeable and straightforward, with stellar feedback, so I'm pretty confident they're gonna be what they're supposed to be. But, being used, even just a little, I'd still like to visually check the internals and make sure they're properly and freshly greased, and dialed in.
I've done a number of overhauls on older Shimano 9 spd stuff, (at least XT, Deore, 105, maybe more), but was wondring of there are any quirks with these 6600 10-spd hubs I should know about, or is the process and tools needed, basically identical ?
Thanks........
