That's a lot of questions.
FDISK should take care of your worrys. I believe the maximum number of
partitions is 24. (There being 26 letters in the alphabet and A and B being
used for Floppy drives).
There may be a limit on size of partitions, depending on the system you
built and your OS. I doubt though that this will have  an influence given
todays hardware. I think the only concern would be the OS you are installing
and the type of partition you want to create.
In terms of using hard drive manufacturers software - it wont harm you. I
use Western Digital's software all the time. Bear in mind though that this
software is usually specfic for a manufacturers drive.
Size of partition for OS? Can't answer that one. I don't really have a
preference, which is what I guess it boils down to. I know some prefer to
have one partition for the OS, another for apps, another for files, another
for.....whatever.
Good luck
