I read in a B747 book that the earlier models had some main landing gear wheels that were able to turn for taxiing purposes...is that true, because I have never heard about this. Thanks

Yes, this is still used and indeed, it was not available on the earliest 747s and a few taxiway runoffs (nothing serious, but enough to get the good people of Seattle thinking) caused Boeing to offer this. There is a "bodygear steering" switch on the pilots' overhead panel (I'm not completely sure about its location - comments anyone?), used for taxiing. The idea is that the bodygear steering would be deactivated during the takeoff and landing.
I'm not aware of any incident where the failure to disengage this before takeoff led to an accident!

The 777-300 has steerable main gear bogies also along with cameras to help show you where you are on the taxiway. These are placed showing both main carriages and the nose wheel. It seems necessary since it's the longest airliner.

The DC8 also has main wheel bogies that caster when turning to reduce tire scrub on the inside bogie tires.
