What kind of adapter do I need to make use of of the in-seat power supply (laptop) on United's 744's, 757's (non-PS) and A320's? I see on Seatguru that the power type on United is EmPower - I am not familiar with this. Any additional information will be welcomed.

United First and United Business on non-p.s. equipment use an Empower adapter and provide up to 70 watts.
iGo, Kensington and Targus (amongst others) make adapters for laptops, DVD players, MP3 players, and other devices.
As noted by UnitedNRT, often these units are either disabled or the ports are covered over. This is especially true in United First on the narrowbodies. You are most likely to find working ports in United First and United Business on the widebodies (especially three-class).
If the ports are off (no green light), politely ask the Flight Attendant to reset the circuit breaker (usually near Door 1L) as the system may work. However, in many cases, the system has been disabled for deferred maintenance.

if it's 70 watts only, I guess I wouldn't be able to bring my laptop with a 130 watt power supply onboard? somehow I picture a 757 dipping and pulling up again in the air as the cabin lights flicker on and off while the pilots are trying to figure out the sudden power loss onboard :p

Depends on the laptop.
My HP zd7000 desktop replacement (3.4GHz PIV / 17" LCD), which has a 135-watt AC PS, could not run from the port, but I could charge the battery if the laptop was off. Also, if I left the battery in and connected to emPower, it bounced back and forth between the two (emPower up to 70 watt load then battery for more).

My job gave me one of those as well. It looked cool in the catalog, but that thing is huge. I would have never tried to use it anywhere outside of a sturdy desk. Why you would intentionally try to take that thing on an airplane is beyond me. I ended up trading mine back in for an nc6000 just so I had something that was small enough to use on a plane or on my lap. The 7000 series is just too big to lug around and unless you're trying to play games on it there's really no reason to buy such a hugely inefficient device.

I wanted a desktop replacement (she replaced a laptop and a desktop) that would last years and would look great playing DVDs. But yes, she was a monster - especially with three batteries to try and keep her alive cross-country.
I'm a Mac user now, so I carry a MacBook 13" with me. They just released a MagSafe emPower adapter so now I'm good to go on UA.
