I checked out your new site. I think its a good start. I like the albumn tool, but there are better looking ones out there, IMO. I'm not really familiar with the names, but I know there are many that are free and easy to integrate into your site.
About the pictures: I think you have to decide what you want your site to be. A showcase for your best work. A portfolio for professional or educational purposes. A running photoblog of your most recent work. An online family-style albumn with tons of pics organized by event or holiday family and friends can view.
Knowing the purpose can help you better select which images to post on the web. I went through this when I got a smugmug account. At first I put tons of stuff on there. Then a ton of holiday/vacation/family stuff. Then just a few galleries to serve as a portfolio. Since I didn't really have a clear idea of what I wanted the site to be, it was very difficult for me to determine which pictures to show.
Anyway, I hope this helps. Visit my somewhat neglected smugmug site here:
