I always use the eoic method to adjust valves, but if you've only got one making noise, and you're sure of which one it is, then you may be better off adjusting it while it's running. Use an old valve cover, or put some cardboard next to the springs to prevent oil getting on other stuff. On the fuel issue, you'll be fine.

Are you sure the ticking is not a bad exhaust gasket? Sometimes they can sound dead-even with a valve/rocker tick

If the car is stock you can run whatever fuel you want due to the engine having a knock sensor. Premium is not a must, but will give you the best performance. Does the tick get louder with the engine under load? II think thef so it's most likely a leaking manifold/header gasket. If you want to tackle this yourself, the most accurate way to adjust them is the EOIC method. Here are some others you can read about:
