I'm not sure about green curry, but I did make an apricot curry and I just used chicken drumsticks and put it all in for 7 hours. Didn't bother to brown it or anything.
Turned out beautifully.

I'd chuck it all in. They reckon the key to cooking well is not not open the lid for at least 4 hours. Only 2 or 3 times max during the whole cooking.
