Welcome! I agree with all of Seven's recommendations. I'd also put in a plug for trying to a local club and maybe go to a star party or two to meet others who can help in person. You have a great setup for visual astronomy and there are plenty of people who consider a 10" dob a lifetime scope. If you don't have one, you might spend the $50 to get a Telrad finder, which I find useful for all scopes, but especially for manual dobs.
Also, even though it is hard (even for me after 20+ years) try not to go crazy reading about what others have here and are using and think that certain upgrades are necessary. The fact is that your scope is able to show you a lifetime of objects. A few more eyepieces might be nice (not essential), but other than that, it looks from your signature like you are ready to go.
