I think the Snow Peak Solo Cook kit posted above by Mike W is a very good place for you to start. Everything WILL nest together in a small package, with your stove and fuel inside the main tall pot. They sell those kits at that big recreational equipment store - go have a look at it.
If you find you need something more later on, Snow Peak also sells a larger pot that Mike W's set will nest neatly and compactly inside. They also sell those at that big recreational equipment store - go have a look.
If you want something still more extravagent, I would add to Mike W's setup plus the outside nesting pot. but not with something nesting. For example, I would add an MSR flex skillet. The flex skillet can cook just about anything - fish, pizza, biscuits. Plus it's deep enough to boil in and use as a saucepot. The extra flex skillet does't really take up any room in your pack if you fill it with other gear, and it "only" weighs about 8oz. I don't think it's important that the skillet nests with your other pots, and I actually think trying to do that is a mistake because you won't get the best combination of pots that way.
The problem with doing much more than that, is you have to clean all these dishes somehow, plus you'll need cooking utensils, maybe plates - it just starts to snowball and you end up ruining the whole experience because you're carrying way too much junk.
