Firefox has a number of plugins which will allow you to download Youtube (and other sites') videos with the click of a button. I use FlashGot + DTA.

The important thing about your dedication is that you *feel* dedicated. You claim to have performed the dedication, so just take a few minutes to think about this: you've formally offered your body, mind & soul to the service of Satan, and formed a binding agreement.
Laziness is a difficult obstacle to overcome, and your best weapon against it is sheer force of will. Just force yourself to sit down (or lie down or whatever) and meditate (and also RTFM).
Some say that it is easier to focus on meditating in the early hours (before sunrise), because fewer people are awake, making their vibrations less powerful, and therefore less distracting.
Another good time to meditate is right before sleeping. Just do a sitting meditation for 10-15 minutes before lying down to sleep.
Also, boredom is one of my favorite resources: when I notice that I am feeling bored, I remember that I should be using that time to meditate, even if just for a few minutes.
There are a lot of ways to join in the battle; there isn't a comprehensive list. The JOS website gives some suggestions. In addition to those suggestions, be creative, and find your own ways to thwart the enemy. The power meditations, rituals, etc, aren't even the bare minimum that you should be doing. In addition to those things, you should be making efforts in the physical world as well. See here:

The Void meditation is tricky to master. Start by building your focus before you try to completely empty your mind. A lot of people suggest that you be mindful of your breathing--just focus on inhaling and exhaling without letting your mind wander. When you notice your mind wandering, it's not a big deal: simply focus again on your breathing.
