Couple of suggestions here. Check out this article in the tech library:

Also, if you have the dingy headlight lens syndrome, polish them out. I use plastic polish and a buffing wheel in a drill. My '94 is especially bad about this, and I polish the lenses once a year, in the Fall before time changes. This alone makes a big difference.
My '94's lighting was so bad compared to my other two (older!) trucks, I added relays and heavier gauge wiring to power the headlights. The tech article describes doing this to the high beams; just repeat the mod on the low beams, too.
Another reason for doing the relay mod is to take the load off of the Multifunction Switch (hi/lo beam switch, or Malfunction Switch as AllanD aptly calls it); these are a major weak link in the headlighting system, along with the thin OEM wiring. Adding higher-draw bulbs to the stock circuit setup can make the switch fail even sooner, and it's really inadequate to begin with.
I'm also running some Sylvania bulbs (sorry I don't have the part # in front of me) which were stated to be 20% brighter than stock, but the cost was about the same as stockers. I've heard good things about Silverstars, and I've also heard that they don't last long. I didn't want to spend that much money for them to find out for myself.
I'm happy with my '94's current setup; at least it's adequate and much better than I suffered with before the mods.
Driving lights and fog lights are typically regulated by each state. Usually the regulations involve "height from road" specs, and in some cases fog lights must be operable only with low beams, and driving lights only with high beams. Pretty basic wiring using relays, in both cases.
Hope some of this helps, and sorry for the novel. I can relate to your lighting problems; I feel like I'm blind in one eye and can't see out of the other one, especially at night.
