I have a Kona Lanai 2011 with the following transmission -

Shimano Tourney EZ Fire Integrated shifters / Shimano Altus front mech / Shimano Altus SGS rear mech / Suntour CW-XCC-T202 chainset, 42/32/22 tooth Chainrings / Shimano HG30 8-speed 11-32 tooth cassette / 24 gears

I use it for commuting and recently when under load (either up hill or setting off from lights) the chain has begun to slip on the cassette.

I average 60 miles a week on it, and have done for 2 years now so I assume it's just worn out. I think I've let the chain wear to far and so will need a new cassette as well.

I don't think it's worth spending a lot on this bike, but I do want to sort this out.

I think to fit this I'm going to need

Chainwise I was thinking

I used to play with bikes a few years ago, and remember that SRAM chains have powerlinks which made it easier to fit / remove. I no longer have my chain link splitter though, I guess I'm going to need one to shorten the SRAM chain to suit my bike? I do remember having problems with SRAM chains when splitting non-powerlink links - or them being stiff when re-adding them.

Am I right in thinking that chain rings wear much slower, and I should be OK leaving them or should I just replace the lot? I have noticed that in the largest chain ring that the gears don't skip. I'd put that down to just the angles that the chain is put into whilst in that ring.

edit; worth replacing the jockey wheels as well? http://www.chainreactioncycles.com/shimano-jockey-wheels-mtb/rp-prod885

Replace the lot. The front rings will be worn too. You will need a chain whip and a bb tool. Have a look at your jockey wheels, they may need replacing as well.
 
It's the cassette that's it slipping on, but for what it costs I'll do the chain rings as well, let it all wear in together.
 
I would just replace the cassette and chain. Do you use the front derailleur much? If not I doubt they will be worn that much so I would keep the existing rings.

SRAM and KMC both use the quick link which is easier to fit. As has been said already, you will need a chain whip to hold the cassette in place while you remove it. Might be useful to have a chain tool to cut the chain down to the same length as your existing one too.

Do you mean cassette tool? cant think what the bb tool would be for?

You'll need:
Cassette tool
chain whip
chain tool

For replacing the chainrings, it would be useful to have:
Crank puller
chainring bolt driver
