A little research here and on the internet in general will turn up dozens of build alongs, with something to be learned from every one. Learning to build is a process of gradual accumulation of knowledge and practice... and it doesn't have an end
Are you looking at doing glass lam or just wood? Can't help with the latter, but if you check the "how to" sections on my site there's a lot of info for you...
www.dickwightman.com The Gallery shows about 20 bows with discussion of woods used and lam thicknesses.
"How I Build a Bow" is a detailed build along, and there is a new build along that is, rather weirdly, in the section labeled "Converting a Sander"... It's a project that just kind of grew. It's almost done (maybe today) and then I'll sort out the web pages and separate out the bow build.
