Lost Applications :(

First don't hard code your email address because the internet bots will grab your email address and you'll start getting spam like no tomorrow.

Secondly, why not take it to an apple store, they'll be able to get you up and running again if you don't have a cd driver.

Thirdly, why not invest in an optical drive at this point? Seems like of logical especially given the need to load OSX via the optical.

fourthly as spinnerlys stated, check out the trash bin as it may be there provided you didn't empty it out.

Finally, sorry to sound harsh but why in the world would you delete those applications?

If you're hoping to have someone send you those apps, you'll need to provide the exact version of OSX you're running. Anything else just won't work
