Recently I added a Texas Instruments TI-99/4A to my collection. Since
then I also bought one in a off white or beige case (I'm not sure what
you would call the color). Was the non-metal case version of the
TI-99/4A a later model? I also need to know if anyone has a schematic
for both of these models?

Try this web site out, don't know if there are Schematics there but its a
really good source of information for the TI-99/4A.. I also have several
of these very popular computers in my collection.

The silver and black model is the original one. The beige, all plastic
case is the later model. IIRC the later model has circuitry which prevents
it from running third party cartridges.

The beige model was later.
I have the full schematic for the TI-99/4a. Keep this in mind but don't
ask me to photocopy it for a while. I'll be tied up trying to get my
collection in order for some time so I won't be able to do it in the short
term.
