all grain advice please :)

[Pat_buttercups]

hey guys,
Trying to get my all grain setup going now i have a cooler can anybody tell me what else i need to make it a mash tun and where i can buy it(B&Q maybe?)
Also need to refill my Hamilton bard and get some more keg equipment and probably a better gas system than the HB, keeping an eye on the for sale here but if anybody knows a good place to get these things Id love to know.
cheers
