You don't remove any capacitors at this stage. Make your lamp limiter and power it up with that first so that you know the state of play before you start. Only then do you assess what capacitors you need to replace. There are several critical ones such as the grid coupling capacitor as has been mentioned. Then there's a couple on the AGC line that should ideally be replaced. The rest of the Hunts can probably be left, as they're not in critical positions and any leakage they have won't stop the set working or cause any damage - it's up to you.

If you start removing and replacing parts before basic testing, you won't know whether there's any failed parts such as transformers that may make the set beyond repair, also you may introduce faults that weren't there before, so TESTING FIRST!
