but get a set if you don't have a metric set; like this:

Snap On is the best, and very expensive. S-K and Craftsman are excellent too. For the casual user much cheaper socket set will usually be okay. I have a mixture of Craftsman and cheapies from Harbor Frieght.

Would this be fine?, So all I have to do is tighten the nut right?
This tool can be used to remove and also tighten when putting back on.
I would remove the crank-arm, clean and very lightly grease the crank.
Replace arm and tighten.
This tool will still need a wrench as well.

[/quote] Sorry to be difficult, but is it just possible just to tighten the bolt on its own without removing the whole crank?

Basically Yes.
But I would remove the bolt and make sure there is a washer under it.
If the crank is loose then it may come off with a tug anyway?
You still need a good socket / tool to tighten the bolt though.

Right, So I tried to tighten the bolt, and it was already tight... so then I thought there must be something inside thats making it wobble, I took it apart to find broken bearing cages!, and a whole load of gunk on some of the parts which I cleaned. Can anyone advise me what to do now? :|
Thanks
If I could see the type of bike (manufacturer and model) I maybe able to see the parts you need.
Good maintenance to your Bike, can make it like the wheels are, true and smooth!
note, with loose balls, your will need 20% to 50% more balls than were in the cages (same size balls) which will result in a significant increase in strength and stiffness. My project bikes without a sealed BB get loose balls, no cages. Sheldon Brown has a good discussion on this also. I use grease intended for boat trailer wheel bearings; inexpensive and will last for a very long time.

Chances are the spindle and races are pitted, inspect close. if you want the best quality repair and plan to keep the bike replace it with new spindle and cups or a cartridge style bottom bracket
