Yes, it's legal. You're simply installing another operating system on your phone. So it's like installing Linux on your PC instead of Windows. In this case, the OS (Android) is open source, so it's legal for people to make their own versions of it.
There was a question some time ago about the legality of shipping Google's own apps with custom versions of their OS. This is illegal. However, you get around this by making a backup of your apps first, then installing the OS without any apps, then restoring the backup of the apps. That way, you've kept your original apps that you had the legal right to own. No worries here, and Google have approved of it.
No. I don't think it would void any of it. Did you have any section in particular that you were worried about?
Yes. It's just the same procedure pretty much, but with a different file on your SD card.
As with any firmware update, you risk "bricking" your phone. If, for some reason, the firmware upload fails mid-load (power failure, error, corrupt file on SD card, etc) then this can result in your phone becoming completely unresponsive.
Similarly, you have to read the instructions carefully. A lot of people end up trying to load the wrong firmware, or wrong radio firmware, for the wrong phone model, wrong network, wrong locale, etc. If you do that you greatly increase the risk of bricking your phone. The wrong radio/firmware combination in the wrong order is the biggest killer here.
After you root... Firstly, lets define what you mean by "root". What you actually mean is "installing a custom firmware". In order to do this you need SU (super user / administrator) access to your phone so that you can bypass the protection systems put in place which prevent users installing their own unofficial firmwares. This super user account is called the root account. So you need to "root" your phone (i.e. get access to the root account) in order to install a custom firmware.
So, after you root, you'll be running a version of Android that has been modified by someone. You will be putting all of your trust in their ability to make reliable and sensible changes to Android, and trusting them to find and fix all "security" related bugs that Google usually fix themselves. The firmware will have gone through no formal testing, no quality assurance, and comes with no guarantees. To balance this, you may find your firmware runs faster, has features or fixes that are only available in later versions of Android, and customisations that improve the overall experience of the phone (such as being able to install apps on your SD card, freeing up vital memory and hence speeding up your phone).
Most people love their custom firmwares, but there are also lots of people who seem to want to unroot for various reasons.
Installing a custom firmware will invalidate your warranty, and possibly any insurance. Some people have kept quiet about this and managed to return their phones, some haven't. It's a real risk.
You will also never get any official updates sent to your phone while you have a custom firmware installed. Your phone will be at risk from any security holes (that become public knowledge when they're patched) until whoever made your custom firmware gets around to finding the fix, implementing it, releasing it, and you update your phone to the new version.

You'd have to check with them. It does affect some insurances.
Widgets are the biggest killer to loading your home screen. Remove as many as you can. Icons and folders are the next biggest killers - remove as many of those too.
When using a task killer - make sure you don't kill any system processes or any other user processes that will simply reload when you kill them - all this does is slow stuff down.
Try and keep at least 20MB of free internal memory.

Just follow the guide. Read it CAREFULLY. If you are unsure about anything then come back here and ask someone. Follow all the instructions to the letter. Read the entire guide first before trying it so you don't get surprised by anything. If something doesn't make sense then ask here first for clarification - it's possible it doesn't make sense because something is not right.
For the record, even a rooted G1 won't have multi-touch. Its screen doesn't support it. There are only a couple of Android phones who's screen can support true multi-touch.
There is, however, a poor-man's-multi-touch that all Android phones can do. But it can only make a guess at where two fingers are placed on the screen, allowing for pinch-zooming. It can't, for example, figure out where three or four fingers are being pressed like the iPhone can.
