If you followed the steps above, you will have been able to create tons of varieties of meta description tags...If you only have a few pages, this isn't worth it, but if you have 100's or 1000's of pages, this is how you make the amount of tags needed to dedoop, with the least possible effort.

The good news is, the meta keyword tag is much easier.

The easiest is to paste about 12 of your best keywords into Tom's Spinz, and grab a bunch and Replacez them, using this as the "find": METAKEYWORDTAGZ

Or, if you have more, try this:

Find:
METAKEYWORDTAGZ

Replacez:
1METAKEYWORDTAGZ 2METAKEYWORDTAGZ 6METAKEYWORDTAGZ 3METAKEYWORDTAGZ
2METAKEYWORDTAGZ 5METAKEYWORDTAGZ 3METAKEYWORDTAGZ
3METAKEYWORDTAGZ
4METAKEYWORDTAGZ 6METAKEYWORDTAGZ 5METAKEYWORDTAGZ
5METAKEYWORDTAGZ
6METAKEYWORDTAGZ 3METAKEYWORDTAGZ

Then take your "best" 100 keywords or so, and split them into 6 lists, performing a Replacez on each.
