No, you're not "fully protected," but you've got a fair start.
WinXP's built-in firewall is adequate at stopping incoming attacks,
and hiding your ports from probes. What WinXP SP2's firewall does not
do, is protect you from any Trojans or spyware that you (or someone
else using your computer) might download and install inadvertently.
It doesn't monitor out-going traffic at all, other than to check for
IP-spoofing, much less block (or at even ask you about) the bad or the
questionable out-going signals. It assumes that any application you
have on your hard drive is there because you want it there, and
therefore has your "permission" to access the Internet. Further,
because the Windows Firewall is a "stateful" firewall, it will also
assume that any incoming traffic that's a direct response to a
Trojan's or spyware's out-going signal is also authorized.
ZoneAlarm, Kerio, or Sygate are all much better than WinXP's
built-in firewall, and are much more easily configured, and there are
free versions of each readily available. Even the commercially
available Symantec's Norton Personal Firewall is superior by far,
although it does take a heavier toll of system performance then do
ZoneAlarm or Sygate.
Microsoft's Anti-Spyware tool is still in beta testing, which means
that it's not "ready for prime time," nor should it be relied upon, yet.
To deal with issues caused by any sort of "adware" and/or
"spyware,"such as Gator, Comet Cursors, Smiley Central, Xupiter,
Bonzai Buddy, or KaZaA, and their remnants, that you've deliberately
(but without understanding the consequences) installed, two products
that are quite effective (at finding and removing this type of
scumware) are Ad-Aware from
www.lavasoft.de and SpyBot Search &
Destroy from
www.safer-networking.org/. Both have free versions.
It's even possible to use SpyBot Search & Destroy to "immunize" your
system against most future intrusions. I use both and generally
perform manual scans every week or so to clean out cookies, etc.
Additionally, manual removal instructions for the most common
varieties of scumware are available here:

Grisoft's AVG is a good product. Be sure to keep it up-to date.
There are several essential components to computer security: a
knowledgeable and pro-active user, a properly configured firewall,
reliable and up-to-date antivirus software, and the prompt repair (via
patches, hotfixes, or service packs) of any known vulnerabilities.
The weakest link in this "equation" is, of course, the computer
user. No software manufacturer can -- nor should they be expected
to -- protect the computer user from him/herself. All too many people
have bought into the various PC/software manufacturers marketing
claims of easy computing. They believe that their computer should be
no harder to use than a toaster oven; they have neither the
inclination or desire to learn how to safely use their computer. All
too few people keep their antivirus software current, install patches
in a timely manner, or stop to really think about that cutesy link
they're about to click.
Firewalls and anti-virus applications, which should always be used
and should always be running, are important components of "safe hex,"
but they cannot, and should not be expected to, protect the computer
user from him/herself. Ultimately, it is incumbent upon each and
every computer user to learn how to secure his/her own computer.
