the tinterweb (what my mum calls it) is the greatest source of knowledge known to man
firstly id pick a venue to learn on, somewhere not to big (10 acres max) as you probably don't want to be casting 120 yards on your first time out and with plenty of fish(I picked a hard water to learn on and trust me its not nice going home without having caught anything on your first 5 or 6 trips) , then ask the local tackle shop for info on the lake
so if you find out its mainly silt on the bottom you've got a starting point for research, that way you don't have to learn every conceivable method of carp fishing and can keep it simple.
secondly is get a marker rod and learn to use it properly, there are thousands of tutorials online (youtube like dayvid mentioned)
