I needed to buy a spacer for my 2nd hand Mavic Kysrium's so my 10sp cassette fitted and my Fulcrum 7s had one which came with the wheels as they have a 11sp hub.
When it comes to indexing there's a great video on youtube, where it explains clearly once you've set up your limit screws you never will have to again (and if they are currently set up correctly don't mess with them). Then all you have to do is concentrate on getting the chain to shift between the bottom two sprocket to index. If it doesn't shift properly through the block after that any problem is due to the cable/shifters and not the indexing.
