Cooking - the camping gaz stuff is fine - but take a spare cylinder or 2 with you! (they always run out when you're heating up water for that 2am / 6am cuppa...). I had a MSR dragonfly stove which was great / bombproof but a little fiddly. We currently use a coleman dual fuel 2 burner when taking the car but it's too bulky to back pack with.

Cooking stuff - MSR pans are great. It's not a bad idea to take a few Tesco 'value' paper plates or the like to save on the washing up!
