Thanks for all the help @DrAzzy.
@Espruino_user_dk as well as R9, you might find that you could solder to the FET (Q2) next to it - being able to solder to an actual component might be easier for you.
Also, as far as soldering tools - I bought what's basically a cheap Hakko clone, and it's completely useless in much the same way you describe (to the point where it's not really usable at all). I unscrewed the end and oozed some thermal paste (the stuff that comes with PC CPU heatsinks) between the heater and the tip and that has helped a bit, but it's still far from perfect.
