I am no pro. I am just a little bit interested and using it somewhere for a product. And it's important that this product use good listed in google ... but it's not too hard.

WordPress: yes, you can use it. But you need to pimp it up with the common seo addons, and you have to use the addon against this nofollow thingy in word press.

own html site: you can use a software like Dreamweaver. It's quite easy to use and makes a clean code and you can still can change things in the code.

bold/italic: nope, u can use it. everything that is in <h1>keyword</h1> (big font headline) is important for google. The same with bold text (but not so important).

free iTouch thingy: well, I personally never would search for "free iPod iTouch", because I don't believe in offers like this. Do you think that some1 would search for this words? I would rather search for cheap iTouch when I am interested in an iTouch. And than maybe click on your link when I see it in the search results.
Before you starting this SEO thingy you have to think about what the peops are searching for, what way people are using/ could use. Make a list with relevant key words / key word combinations; and read seo boards.

... and np, you are welcome ;)
