Looking for applications (freeware)

I've started to get into refurbishing old PCs and I'm also thinking about setting up a set of applications I can (and will) throw on them.

Right now I have:

System drivers

Security:
AVG Free
AdAware
Spybot Search & Destroy

Utilities:
CleanCache 3.0
ccCleaner

Productivity:
Deepburner (thank you for the suggestion geoscomp)
OpenOffice

I'm also debating if I should get ghost and throw a ghost image of the system on a DVD - would the person need Ghost to restore or would the DVD be bootable (or are there any free versions I could include with the system?).

Any other suggestions I might want to include?

In use CDBurnerXP - works well.

edit" MalwareBytes is an excellent product at this time.

Save some $$$ and buy an older version of Ghost, it will make a bootable cd or dvd ( It will span cd's or dvd's if the image is large ) You may also Ghost to another smaller hard drive and leave it inside uninstalled for emergency recovery as I usually do with trouble customers.

I've been trying A-Squared Free bundled with On-Line Armor Personal Firewall. So far not too bad and the firewall isn't as hard to figure out as some other companies. Also my opinion is that Ad-Aware doesn't compare to Spybot or A-Squared. It seems like Ad-Awares quality has been steadily declining in the past few years. I see more and more things get past it.

Malwarebytes rates very very high.
