OK now, my gas pedal is really wobbly and tends to "catch" when I try to depress it. It's like the plastic part that grabs the metal lever underneath is somehow broken. Is this a common thing? Do I need to buy a new gas pedal, as my shop has said? Or is there some simple fix I can't find?

They are not an common faliure so there are lots of good used ones out there.

If you look at the back of the pedal you'll probably find that the socket moulded into the upper part, that the ball of the linkage pushes into, is cracked and/or worn. Only a new pedal, or a used one without that issue, will fix the problem. Check a used one carefully. Lack of lubrication or grit accumulation accelerates wear.

Edit: Checked new prices online and they're cheap. If it was me I'd go for a new one.
