Hey Dutch -
1. Audio is synced with video, except in some cases on windows, in which case you need to add a 2 or 3 frame delay to the video to resync with audio. You should be fine on a Mac. 
2. If the video from the tutorials looks laggy on your computer, it's maybe because of a few reasons. The tutorial videos are short loops that illustrate concepts of interactivity, and several of them are operating at a fairly high level of computation, so if you are looking for straight forward playback, you're probably confused by some of the advanced tutorials, which are inherently jumpy because of the control settings, such as the mouse watcher tutorial. You should also optimize your machine when you use Isadora - ie, don't have other programs running in the background unnecessary. Follow the manual's instructions on setting up your preferences to get the best performance, as well. There are definitely ways to get great looking video using Isadora.
3. Yes, you can play 2 projectors to 2 separate outputs. This is limited by how many outputs you have available, and the best (most affordable) laptop solution available at this time is the Matrox Dual or Triple head2go.
4. Not that I know of, not directly at least. You will need to go DVI to RCA to F plug adapter, so you need a secondary adapter. Look to Radioshack for this.
5. This requires a little bit of work but it's a great solution. However, if you're a total novice to video installations and Isadora, you might find yourself a bit confused. There are plenty of threads on this forum regarding the triple head 2 go setups, and Matrox has a decent knowledge base to draw from in setting this up. The simple answer to your question is Yes, you can send out video to 2 separate projectors and manipulate it on the fly with only one video card. You run into some issues here, though, if you plan is to send one signal to a real video projector, and the other signal to your old TV sets, which requires a bit of signal adaptation. You'll need to send your VGA signal to a scan converter to convert to RCA and then to another F plug to RCA jack adapter to get to the TV's.
Ultimately, you need to read the introductory pages in the manual about how to optimize your footage, your machine, and Isadora for best results. Don't skip the manual, it's there for a reason, and you'll find some really handy tips and tricks in there. And stay positive, there's a reason why hundreds of us are using Isadora for everything from theater to VJ'ing to art installations.
I hope this helps. I'm sure other users will pipe in with some advice. Good luck!
Cheers,
William
