The limit screws and B-screw settings are the same as they always were. The key to trimming is to do it based on the 2nd or 3rd high gear sprocket. You can't use the high gear sprocket because the cable is slack and the trim depends on the limit screw (just as always).
Cross-chaining likewise is unchanged. You want to ride on aligned combinations as much as possible. Cross-chaining isn't digital, as in some combinations are OK, and others aren't. Just keep in mind where you are, and avoid using the most crossed combinations. One issue that doe's uniquely affect 10s vs older systems is clearing the big ring when riding small with the outer rear sprockets. The chainrings are closer together, and so more sensitive to the chain's angle when coming from the outside. How much this limits small/small pairings depends on the chainline, the difference in chainring size, and chainstay length. You'll know when it's an issue, and make a mental note to avoid thoes pairs.
