wiring fan/light combo and 3 way switch

No, to hard wire it you'd need two sets of three conductor cables between the switches and two circuits from one switch location to the fan light. There are fans made with electronic controls like Casablanca "Intellitouch" which would work. There are also some aftermarket transmitter receiver kits that may work as well

Am I better off to replace the one 3 way switch (that has the dimmer and fan control bult in with a regular 3 way switch and use that to control the light, and either use the pull chain for the fan, or maybe a wireless unit as suggested?

The combination dimmer/speed control is useless without a three wire cable going from that box to the fan. If you wanted to use a pull chain for the fan, the lights would have to be on first, or there'd be no power at the fan. I would look into electronic devices to do this, or like I mentioned Casablanca makes multiple switch location "Intellitouch" models

That depends on how it's wired. I had one fan to convert (previously both light/fan on switch loop, now only light on switch loop). It was easy to do since the way that room was wired, there was already a hot connection in the box over the fan. Now the light switch controls the light only, not the fan.

The OP already stated his feed is in the lower switch box.
