Transfering your VHS tapes to DVD is a great idea.
If you have not used disk imaging / cloning software to transfer it to the new drive, yes. You can still reinstall with the disc, however.

The only way to get true 2-wheel drive would be to replace the transfer case.
Changes are that it's a fan and not the hard drive. However, if it is the hard drive, chances that the internal bearings are going bad. I'd replace the drive and transfer the contents as soon as possible, before the drive completely crashes.
YES. But you will have to get a 2-wheel drive 4L60E transmission to replace the 4-wheel drive transmission. Reason is that the center shaft that's running through the 4x4 transmission is longer so the transfer case will slide up on it. The 2-wheel drive center shaft is shorter cause there is no need for a transfer case.
You should check your laptop manufacturer's website for details on how to replace the hard drive. If the drive is user-replaceable they should have the schematics on how to do so. When you replace your drive, remember to get a drive of the same speed. If you get a faster one, you might cause too much heat build-up in the case.
DVD is a perfectly safe way to store media,no need to clutter your hard drive.
Replace the transfer case , had same problem and that's what it was.
It depends on the 4-wheel drive system of both vehicles. Both quadra-drive and quadra-trac II use the same transfer case, called the NV247. If both vehicles have one of those 4X4 systems then yes, they are the same exact case and can be used to replace each other.
it should cost $40-$50 depending on what you drive
It is no possible for a human to replace its head.
It depends on how many miles you drive, and how long you want your car to last.In General you should replace the engine oil and filter, the transmission oil and transmission filter and drain and replace the radiator coolant.You should also replace your air filter,and if your car has an external fuel filter, replace it.If you drive a lot of miles, your engine oil may need to be change sooner.
