Also, I got carried away and picked up a few spices I'd never used before and so far haven't found too many recipes that actually use them. Any ideas of curries that really make the most of mustard seeds, fresh curry leaves and black cardamon?

I like curry leaves a lot (fresh). They work really well in anything South Indian. They have a distinctive taste that you will know when you taste them (if you like South Indian). Curry leaves and coconut milk go well together. I like them in a tarka for dal as well.
Black cardamom has a smoky flavour so anywhere you want that. Again in tarka dal, in a nihari gosht, good in a keema or laal maas. Typing this, it occurs to me I like it with lamb. Never thought about that.
Mustard seed in anything Bengali inspired. Again, good together with cumin seed in dal, or in saag aloo and bombay potatoes (just about anything with potatoes). They work well with curry leaves in South Indian cooking.
Lots of fun playing with Indian spices. So much diversity...
