My recommendation: don't waste your time with the online stuff. Get a good book and work through it, setting your own pace. Practicing scales in isolation is boring and off-putting. Make music from day one.
Steve Kaufman has gotten me hooked on bluegrass - his books can be had new or second hand. Each one is months and months of good times and you'll be pretty good by the time you're done with them.
