I'm just starting to get into woodworking again, having not really done much at all since high school wood shop (so, about 15 years). I just ordered my very first set of chisels from Lee Valley - the 4-chisel Narex Classic Bevel-Edge set and a single 1/4" Narex mortise chisel. I figure these should set me on the right path and give me some decent tools to start out with. I also ordered the Veritas MKII honing guide to help me get them sharpened up.

But being a newbie to true woodworking, where should I start with these chisels? Do they require some preparation before use?

I've read posts about people flattening the chisels before sharpening. Is that something I'll need to worry about, just starting out? Or should I just concern myself with getting a nice, sharp edge on them and dive into some practice cuts? Where would you recommend I start, once these tools arrive on my doorstep?

Also, are there any good places that might have lessons to watch/read and practice how to use chisels?
