Do those 20 WinXP PCs have some kind of anti-virus software on them.   Even with a firewall, it's best to have anti-virus software installed to detect viruses, worms, and trojan horse programs.

"...log the traffic from them to outside" - that's very ambitous...if you are to protect content on the clients from being sent to the internet, you should think about solutions like clearswift's mimesweeper or finjan's content control. Those products inspect the content for keywords in the metadata (like "company confidential" or "nato restricted" or whatever) and prevent such data from reaching the internet.

For the other requirements (protection against worms, viruses and spam), you will have to give a detailed setup of how they connect to the internet and what e-mailing solution (client and server) is used.

Good suggestions above. Your requirements are broad and ambitious, and a lot depends on what you're trying to protect. For example, if you're working for a bank then it's different than for a school. You will want to approach this in multiple ways, i.e. a firewall and anti-virus are both important, but only as part of an overall plan that includes other elements.

It would help if you told us what was most important (e.g. is this a high-security site like a bank, or do you just want to make sure employees are not wasting time).

Some things you definitely want to consider are: (a) Backups (b) User Education (c) Security updates and scanning (d) Firewall (e) AV and anti-malware software (f) configuring the PC's for least-privilege etc. If this is a high-security requirement you should look at encryption. Don't forget to enable the firewall on individual PC's. You need both and AV and an anti-malware program, but don't install more than one of each. To protect from spam you'll want a good anti-spam filter, a lot depends on what you're using for your mail server.

User education is very important because there are a lot of "phishing" or social engineering type threats that get around all barriers you may put in place. This should include explaining to users about how to tell the difference between a real email and a fake email, why they should not install or download "free" things, how to browse the web safely, how to know when something is not working right, etc.

Finally, regular backups will save the day when all else fails.

I should have added:

A lot comes down to your own vigilance, and that of your users.
No point having a backup plan if you forgot to make sure it is running every night.
No point having a firewall that is not configured properly.
No point having AV software if you forgot to update it every week.
And so on.
In other words, it is more of an ongoing process than a one-time fix.

Take a look at www.questeq.com/cymphonix

I've yet to deploy or even request a trial box, but it might HELP you.
Again, this is PART of a LARGER plan, it is not a solve-all.
