first thing you need to do is fix the choke switch, there's no point doing anything else until it's fixed
with the oil window, hold the bike upright (not leaning on the kickstand) and get the oil to sit at the top of the window
once you've fixed the choke switch, if you can't get the bike to idle with the choke off you need to tune the bike (idle screw, air/fuel)
all this screwing around with the choke on has probably fouled up your spark plug too so take it out and give it a good clean
