Personally I would remove the shadows and keep all text flat (no embossing or highlights). I think this will give you the most flexibility for different media types (card, website, shirts, or vehicle lettering). I don't know how well the embossing or drop shadows would translate to shirts or vehicle lettering. i think you'd have to do more vinyl around the logo for the drop shadow instead of clean lines for simple text without any embellishments. Plus additions those design "flares" now may date your logo in a few years as design trends change. Clean and simple will always be in style.
I also agree with adding color to the line, I think that would make it stand out more.
I don't want this to sound like I'm putting down the design in anyway, I think it's an amazing design and really creative name. Really looking forward to the end design!
One more idea, maybe make the dot in your web address the same color as the line in the logo if you choose a color just to make it easier to identify quickly. You'd want people to see your web address quickly on the road and I think that would help.
