You don't really need to change the gaskets every time you adjust the valves. I have adjusted mine a couple of times plus I have pulled the covers off 5-6 additional times and have yet to replace the gaskets that came with the motor. The trick is using a little dab of wheel bearing grease to hold the gaskets to the cover.
The slack in the steering might be solved by adjusting the "screw" on the steering gear box. I have not done this, but there are plenty of write ups on the samba.
Otherwise, congrats on your first outing with the Orangesicle!!!
