>1. if i use the 55/60 watt bulb do i have to upgrade my switch

No, but you will greatly reduce the electrical load on the switch by
using a relay to control the lights.  Switch turns on the relay, relay
activates the lights.  Switch only has to carry enough current to
activate the relay.

>2. Will i notice a light output increase

Yes.  Even more so if you use a relay and 12 gauge or better wire to
supply power to the lights.

>3. what the ph*** is a park light???

Small 5 or 6 watt lamps inside the headlights that are wired into the
parking light circuit (headlight switch first position) and supply sort
of a soft glow out of the headlight reflectors.  Doesn't light up much,
but looks trick, and useful when pulling into a campsite late at night
when your neighbors are asleep.  Kinda surprised my mechanic Tuesday when
I had the van in for state inspection, but he was cool about it.
