The basics to SEO apply here, and are the same for any technology.
Those controls should not impact your SEO, as long as you have made up for it in HTML. Just make a great website first.
First you need well formed HTML, with completed attributes such as the iamge alt=""
So test your website page on a HTML validator and fix all the errorshttp://validator.w3.org/
Use of the H1 and H2 tags are good for organizing content, but the title element and description element are priority one. The description element inserts that description in your search engine index record, so they don't do it for you. This is the text people will read to determine if they have any interest in your page.
Use as much HTML as possible, and limit text in images. No duplicate page titles, no duplicate pages.

You have to have a sitemap.xml file, and should have a robots.txt file as well.
