Congrats on your Bull. To answer your question though, yes you probably have all of the "Basic" gear needed for return hunts. Keep in mind though that there's always something new you will want. I've been elk hunting in AZ and now Montana for 18 or so years and I'm always buying something else. Either upgrading the gear from what I have or buying a new "toy".
Keep in mind also that the type of hunt you want to do will determine what gear you need. If you plan to go on an outfitted hunt where the guide does everything but pull the trigger, you need a good rifle/scope, good binos and good warm clothes. Everything else you can get by with what ever you have. If you decide to go all out on a back country DIY hunt, you are going to need allot more gear (Good pack with a frame, good boots, etc.) So it all depends on what you plan to do in the future.
Congrats again
