Three Questions from a Linux Virgin

[sreynolds at internode.on.net]

Yesterday I installed Fedora on a stand-alone machine at
home.

Q1) When I mount my USB flash drive I can only write to the
drive as root. I logged in as root and tried to change
permissions for all users to RWE (777?), but I get a message
that says that I don't have permission to change permissions
on the flash drive. I thought root was god, so my wild guess
is that there is something wrong with my entry for sda1 in
fstab:

/dev/sda1  /mnt/removable  auto  auto,user,rw  0 0

Is there something wrong with this entry?

Q2) What's the command to change file and directory
permissions recursively down through a directory tree.

Q3) I have a reasonably new Canon LBP-810 laser printer that
I can't print to because Fedora doesn't have print drivers
for this printer. I've googled for printer drivers, but
can't find any. I've googled the problem and it seems Linux
cannot support this printer. The only solution that I can
find is to run a widows printer server and print through
that. This isn't a solution for a single stand-alone machine
at home and of course I don't want to network two machines
and run two machines just so that I can print.

Is there a solution or has my printer denied me access to
the wonderful world of Linux?
