hi mate, norm is your man for selling the cornies. email him at: email@example.com
, he will give you a price which includes gas disconnects/gas bottle if you need it, taps etc. its the best of gear he sells. it is quite pricey though, for a general 1 cornie including all the stuff and a party tap. your better of getting 2 as the gas bottle can serve 2 cornies. if you do a search on youtube for 'craigtube kegging' there is 4 different parts but he explains everythign from sanitising to re-filling and force carbonatio.
other good vids id recommend

when you keg in a cornie your basically missing out the 2nd fermentation stage in the presure keg or bottle, it depends how carbonated you like your beer., i usually have it at 10psi for a week then start drinking it.
