pond pumps are usually 240V AC powered.
keep pond pump separate to lighting power so it doesn't fry your lighting power supply when you accidently dig up the power line - plus mixing inductive loads (e.g. motors) and fixed load devices (incandescent bulbs) isn't a great thing. i don't mean a separately fused circuit, just not from the same power supply (if you are able to find a 12V pump)
as for your lighting power requirements, a 12V 20 Watt halogen requries about 1.7Amps to keep it lit. So a 25Amp switched-mode DC supply could keep 14 of them lit.
simple equation to work out DC current requirements: Watt = Volts * Amps
if you want to work out AC current requirements it gets a little more confusing.
