Color photos are essential. Use Picasa to do your edits. Heck, even if you stylize them like you would in Instagram (which Picasa has all that in it now) would be better then B&W. Your work is way too beautiful to not have in color. And your target audience is Millenials who are already into Instagram and that style of photo, so even if you changed each photo to vignete or amaro, you are speaking their language, making your photos look "cool" and they will be in color.
Studies have shown that webpages with content that fit all on a user's screen with minimal scrolling or clicking do the best. Having all those images listed one after another like that is a killer! Your average customer is going to do what I just did - look at maybe 5 the click off your page.
I recommend using a gallery creator like I have on my page, called Simple Viewer http://www.simpleviewer.net/products/. It's free, super easy to use and add to a webpage. The only downside is it's Flash so although the thumbnail photos show on iphone/ipad, you can't enlarge the image. But I love it - it was by far the easiest way for me to quickly add photos to my webpage without having to re-code or mess with anything.
