SmellyGeekBoy has the right advice about the majority of dance music being in 4/4 time, 4 beats to a bar (or measure) etc... Simply listening to the tracks is enough to get the gist of this bit.
One excellent method of learning to line up the beats on both decks is to have two identical copies of the same record. Have both pitch sliders at 0%, have your crossfader in the middle (don't worry about headphones at this point), cue both records just before the first beat at the beginning, and start them at the same time. Due to mechanical limitations they are going to be out of sync giving a kind of echo effect, but they'll be at the same BPM already. Move the crossfader between the decks repeatedly, which one is ahead? Drag the ahead-playing record very slightly for a fraction of a second, and then move the crossfader between the decks again. If that record is still ahead, drag it again.
Eventually you'll reach a point where both records are playing more-or-less exactly the same point at exactly the same time, for technical reasons you'll hear a "phase-shift" effect when this happens. If you drag the ahead-playing record too much, it then goes behind the other record. You can then either drag the other record that's now ahead, or you can speed up the behind-playing record temporarily, either by giving the record's label a push or twisting the spindle in the middle. It's vital to learn both dragging to slow down the record, and pushing/twisting to speed up the record, since when you mix live you'll only be able to manipulate the "coming next" record.

Sort of. My market was weddings and birthday parties and I already had a massive CD collection of Top 40 tunes past and present, so I used a Denon 2600 pitch-controllable twin CD player with mixer (as featured in
this video (not me!)). WIth the help of some extended dance 12" mixes on CD singles I learnt to beatmatch with it at home.
Instead of dragging/pushing records you either spin a knob or use "pitch bend" buttons, but otherwise the principle of beat-matching is exactly the same on CD. Often at discos I would beat-match two typical Top 40 singles and quickly mix across them, so people were already dancing to the next record by the time they realised it began.
I've never tried mixing with turntables, though I'd love to give it a go sometime...
