Not bad at all it looks like you did some good research but
make a copy of your entrance page and remove the " <!-- discription -->"
and ame the name of the file one of your keywords.
No you just have to sit back and watch to see how you show up in the ratings.
You might want to (you may have done this already.) tailor make your
website for each search engine. so you might make up to 3-5 pages of the
main page so you can at least try to be as high as possible on each
copy and rename the index.html to old.html or old.htm
