I think a bar might work and that testing would be the best way to see.

The point about pricing in particular is that there is a huge button in the middle of the page, and people are still not clicking it. My instincts are that a black bar at the top of the screen would be nearly invisible to these people, many of whom are more advanced in their years than the average HN user.

Currently you have no real user feedback on any of your buttons other than cursor change. When a user hovers over a button I would suggest defining a hover state for the button.

As for the "view plans and prices, get started" I believe a smaller button that is better positioned with a hover effect would get significantly better results. Even a simple change such as changing that text to something a little shorter like "Get Started Now", "View Plans" or " View Prices" will get you better results.

Ultimately I believe you would see significant improvements using bootstrap across your site. Some examples of what others have done with bootstrap can be found here http://builtwithbootstrap.com
