Electrical is very easy to learn. The basics are very simple. Much easier than plumbing, framing or drywalling. In Ontario you need to call the ESA (Electrical Safety Authority) and get a permit to do you own work (probably the same in Quebec).
First thing is to plan your circuits. For a 15 amp circuit you should have no more than 10-12 receptacles and/or lights and for 20 amps I think you can put 14-16. It's best to run the receptacles (outlets) on a different circuit from lighting. That way your lights don't dim when you amp or other poser hungry device kicks in.
While the walls are bare after the framing is up you can drill holes to feed the wire through. Make sure that you drill though the center of the 2x4 so that there is at least 1 1/2 inches of wood on either side of the hole. That is to prevent someone from putting a finishing nail or drywall screw through the wire. You can get metal guards to prevent that also. Use metal or plastic staples every 4 or 5 feet to keep the wire in place and have only one wire per staple.
Mount your nail on receptacles about a foot to a foot and a half off the floor (go with what the rest of your house used). Make sure you have a receptacle in place so that if you took a 6 foot cord you could reach every spot in the room.
Nail the switch boxes 4 feet or so up the wall. Ensure pot lights are I/C rated if you are putting insulation around them and be sure to leave an inch or more space between the can and any wood. Plan out your lighting before hand. Check out

I have my sconces and recessed lights on two different zones. I'm using Lutron Grafik Eye, bu two or more separate dimmers does the trick. I'd recommend good quality dimmers for a HT room.
3 way switches are a little more challenging. I found this site very helpful:

If getting electrocuted is your worry about doing your own wiring you can have an electrician inspect your work and tie it into the electrical panel. In Canada the ESA permit only allows you the home owner to do the electrical work. An electrician has a different "contractor" permit that they get to do work on your home. I have to emphasize that you need to get a permit. Your insurance company would like that, and it could save your life. Through the inspection process the ESA might find something that you overlooked.
Just my 2 cents.
