If you want to be sure you have gotten ALL the air out, pressure bleed them. You can spend a lot of cash on "real" pressure bleeder, but I've made a lot of them with an extra fluid reservior cap, an old valve stem and a piece of rubber (cut from an old inner tube or the like). Cut a piece of rubber to fit the inside of the cap, drill a hole in the cap and rubber, shove the valve stem in from the bottom side. You can glue it in with some type of sealer if you want, but I've made it work with just pressure.
Now, fill the reservior with fresh fluid, screw the cap on it, and then use some type small hand pump to put just a little bit of air pressure on the top of the fluid reservior. It works best with a helper to keep a little pressure on the reservior without putting enough on it to bust anything, and to keep an eye on the fluid level. Anyway, with pressure on the resevior, crack the bleeders one at a time until clean fluid with no air runs out. The order you bleed them in doesn't really matter if you use pressure, but I still use the order RetBugtech suggested. Not only does this get ALL the air out of the system, it gets all the old fluid out as well. Fluid absorbs water over time . . . and over time that water causes corrosion. If you change your brake fluid every two years or so, you won't believe how long the hydraulic parts of your brake system will last.
And as already suggested . . . Adjust the shoes tight, bleed (by whatever method you choose), back off on the shoes just enough so you can turn the wheels. Drive a couple of days, re-adjust. Despite popular belief, when you get 'em right, Beetle brakes will stand the car on it's nose. Well, maybe not quite that good, but they will work great when you get them right.
