I just started delving into this a couple of weeks ago. I had a Rockler jig sitting in the garage unused for a couple of years and decided to learn by hand first and then try the jig.
I agree with Holmz and Thistleman, except that it took me 15 hours to watch the David Barron videos, another 2 hours to watch the Rob Cosman videos, then a bunch of chisel sharpening videos, all of which are extremely addictive, and then a long time to actually cut each corner of my first drawer, with more video watching in between. So several days for one drawer.
The first drawer looked horrible, but I was very satisfied anyway. Did 3 more drawers with the Rockler jig, and knocked them out pretty fast. They look great at least to me. Much easier, less frustrating and slightly less satisfying. Now, though, I am going to do some more practicing by hand, and this time with some soft wood. Trying to learn the chisel thing with hard maple was frustrating.
The Woodcraft guy said he personally liked the Western saw but nevertheless recommended that I start with the Japanese saw, and I liked how it worked (it was also cheaper). I was surprised by how fast it cuts. I also would recommend getting the coping saw like they show in videos. Not much $$$ to save a lot of effort.
Of course, these are all recommendations from someone who has now finished a total of one bad drawer by hand and three decent ones with a jig. I can't show you the way and the light for dovetails per your original query, but maybe comments from someone still in the early stages of the learning curve will be helpful.
