Creating a more professional look.

I'm trying to create a more professional look for my blog. I switched to this template, but it's thrown some of my pictures out of wack.  I'll come back and try to straighten that out later. I like the look because I want to showcase certain Web 2.0 tools that students will use to demonstrate learning and this template seems to do that.   Also, I beginning to think that it might be in my best interest to create a series of blogs dedicated to addressing the various state standards individually.  One thing I noticed about other educational blogs is that there is so much information, it's easy to be distracted or discouraged.  Since my audience is primarily thirteen year old math students, I think that it might be beneficial to target something specific, like scientific notation, individually.  Different pages could address different aspects of scientific notation from reviewing exponents to division.  I could also create a page targeting administration and parents in which I outline lessons and expectations that students would not necessarily have to look at.  Any suggestions?
