At this point, I wouldn't worry terribly about working explicitly to create a "bond." In all honesty, that great bond, relationship, whatever you want to call it, will pretty much start to happen on its own when you start to work on being an effective leader and communicator worthy of respect. Properly implemented, respect-building exercises are also relationship-building exercises. Rider/handler safety first, horse safety second, best buddies third.
Groundwork can be great -- you want to be able to control his whole body on the ground, and have him willingly and respectfully yield his body to your requests. If you don't have respect and control on the ground, getting in the saddle won't make things any better. Some specific activities to look into are backing up, yielding the forehand and hindquarters, sending exercises, and NH-style lunging/roundpenning. Saddlebag's recommendations are excellent.
Make the right thing easy and the wrong thing hard. Ask, suggest, encourage/tell. Be consistent, and be effective. Reward the smallest change and the slightest try. Be a leader -- tyranny gets you nowhere, but don't take any carp, at the risk of your fella deciding that he is the one most worthy of the leadership position in the "herd."
I very highly
recommend working regularly with someone who is experienced with green horses and green riders, and can help you to become an effective communicator and leader for your horse. I see that you're in the process of moving and getting things organized, but really, the sooner you get some reliable on-site help with this the better for you and your gelding.
At this point, my biggest concern would be that he may be learning that bucking is an effective way to remove something annoying and get out of work. Once a behavior like that becomes an ingrained habit, it can be tough to break. A friend of mine had a filly that learned that trick early on... before the smoke cleared they had to enlist a local bull rider to stick to her long enough to teach her that bucking isn't the way to get what she wants. They were able to work her out of it, and she became a good equine citizen, but she was a real booger for that first year or so.
Good luck, and ride safe!
