Really, I'd start by changing the chain and only change the cassette if you notice problems (in particular skipping) afterwards. A Cassette will easily set you back another $30 (though being from the UK I'm not up with prices your side of the pond), and you'll have to buy two more tools if you want to change it yourself. I'd save myself the expense and only go there if needed.
Also: judging from that pic, you want to lube that chain. Shifting may well be easier after that.
