I'm no expert on samba and have had problems in the past, primarily
with Windows XP *Home*, which seems to be more troublesome than Pro.

Anyway, my situtation is I have Breezy (dist-upgraded in stages since
the first release of Warty), a PC with Windows XP (Home), a
work-related Thinkpad with XP Pro and an iMac G5 (OS X 10.4). They all
can connect to each other. The kids type CMD-K or something on the Mac
to get to their home directory on Breezy (smb://breezy/homes). On
Breezy, they use Connect to Server under the Places menu to connect to
their home directory on the Mac and I've mapped a drive to a share on
Breezy for the Windows XP Home PC. The two printers in the house are
shared by the Mac to Windows and Linux.

The kids know how to run smbpasswd on Breezy to create or change their
samba accounts (the have the same usernames on all of them, and
probably use the same really bad passwords on all, too -- these are
teenages, after all).

These are the configuration parameters that differ from yours. I don't
know how many or which are necessary:

server string = %h server (Samba, Ubuntu)
wins support = yes
   security = user  (this is commented out in yours)
guest account = nobody (again, this is commented out, and probably
should be in mine.)
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

# I doubt these are necessary, but they don't break my set up:
 domain master = yes
 preferred master = yes
 local master = yes

My home directory shares are set up like this:
[homes]
   comment = Home Directories
   browseable = no
   writable = yes
   create mask = 0700
   directory mask = 0700

And I have a wide-open dumping ground share like this:
[shared]
	path = /home/shared
	read only = no
	guest ok = yes
	available = yes
	browseable = yes
	public = yes
	writable = yes

That's it. I hope that helps.
