The easiest replacement is a Dorman plastic fan, which is a good deal at Advance Auto Parts if you buy online and use their 40% off coupons, though you might have to buy more stuff than a fan to get to the minimum purchase. I sprung for the fan clutch tools since I didn't have them, and a few small things.
It's pretty common for the stock fans to go at this age. The metal fans I've seen have all been for the 5.0 V8, though I imagine they might fit with the right spacer/adapter, but it will probably weigh more. The Dorman plastic fan says it's an "improved" design over the factory fan, and even though it's a 9-blade, there are reports it works just fine as a replacement for the 10-blade factory fans on automatics. Companies like Depo make aftermarket 10 and 11 blade fans if you want those (also rather inexpensive online, $20-40), or you can just hike it to the salvage yard, or maybe find smaller auto parts stores that can get stuff other than the popular Dorman replacement.
As for electric, that depends if it's worth your while to get into all that. Some people have had success and a little better throttle response without the fan resistance, others have had cooling issues. Personally I just stick with the fan clutch, and have a new Dorman 9-blade as a backup for when the factory fan goes...or maybe I'll just replace it next time I'm in there and let the factory one stay intact as a backup.
Radiators don't have A/C connectors...that's the A/C condenser in front of the radiator. Pull the radiator out, then once you disconnect the A/C, you can pull the condenser. That will improve cooling quite a bit, but you might want to put some kind of metal screen/grille in front of the radiator for protection, since the condenser won't be there anymore. You might also sell the condenser if it's still solid and you won't use it, and the compressor as well.
