A great place that set me up on kegging was kegconnection.com you can purchase a kit depending on how many and type of corny keg you prefer. Co2 tank , kegs , regulator, and hose and if you get a kit with shanks ( refrigerator conversion kit ). Everything comes made up hoses attached and all.
And good luck
In bottles -- Sierra Nevada clone and St. Paul porter.
In keg conditioning -- breakwater pale ale
In fermenter another St. Paul porter
Up next !!!! Based on how the breakwater smelled and tasted going in keg !!!
It's up again !!! And haven't even had one pint. :-)
