Red curry recipes

I bought some red curry paste on Amazon after reading that it is one of the better brands and is hard to find in the store (the name is Maesri). I found a recipe that sounds pretty good and basic but it calls for Thai basil and Kafir leaves. Any idea where I could find those? I know I can improvise with some annis and citrus zest but it will not be the same. Also, anyone have some great recipes that use red curry paste?
