You should read and learn a lot then. There are many tutorials on the web. Use google.

Magento is resource hog,
Solution for 1.
so it actually contains a lots of info about seo. you can easily optimize magento according to search engine.

solution for 3.
yep, you should buy ssl while hosting your domain on Hosting Provider. he will enable ssl and will charge $10 -$30/ year(depends according to service provider)
