Yes, it's absolutely worth it.
While you are already doing the redesign, I would recommend going over your entire site for any SEO improvements you can make.
Just based on what you have there, you can improve the SEO friendliness of the site by using keywords seperated by dashes to name your pages. Instead of "us.html", change it to "about-training-reality.html" or something more descriptive to the search engine.
Also look at renaming your images in the same way to allow the search engine to make more sense of them. Instead of "towerlogo.jpg" or whatever it is, name it "training-reality-logo.jpg" or something like that, and be sure to use the ALT tag to describe the picture to a visually impaired person (Google loves this).
