There are no stupid questions.
And, yes, you can unplug your hard drive from your Mac (or just leave
it turned off and connected) and only use it when you want to.

Not necessary to leave them connected, or powered up. Firewire as well
as USB are hot-swappable. I would never use anything but FW 800. Most
desktops now come only with the FW 800 permutation rather than 400.

To answer your question directly, no, there is no larger drive anyone would recommend. You need to go to external where you can build collections or arrays.
First, use one cheap, 2TB USB for Time Machine (assuming you are not already). With a full 2TB drive you are at much higher risk of severe data loss. Do not go below 100GB freespace.
In your case, I'd clone all archived media and exclude this from TM. No point in "wasting" TM on archival materials. Let TM do what it does and provide you a "history" of meaningful data. Your archival stuff should be cloned once, or burned to disc.
The media clone might also be USB if you don't need fast access for editing or processing. Alternately get a Blu-ray burner and start cranking out BD-r for long term archival. That's 40 discs per TB, about $100 of media and 40 hours of burning, but if the media is valuable, it should be archived to optical at some point and DVD is entirely impractical. Allow the discs to verify. Yes, it's a huge time sink, but these are archive discs.
You can use HD for backups (I do) but these must be managed. Can't just put them on the shelf for a decade like you can optical. Hard drives need to be "checked" periodically.
For real-time access on external drives, you want FW800 (twice as fast as USB in real world). For externals, you can get larger than 2TB but these are actually arrays (multiple discs inside). This increases risk of failure.
Chaining FW800 is great but slows performance. Four is the commonly accepted "safe" limit in my biz, but you can theoretically chain... 16?. Three or more will cause ~40% performance decrease. Tolerable in most cases.
No, you don't have to leave them connected. Remember to "eject"! However, be warned. iPhoto is very, very bad with "off-line" media. Try to access "off-line" files with iPhoto and you will practically lockup. iMovie WILL completely lock (at least version 8 does). iTunes is better, but still handles it poorly from a usability point of view.
Arrays are great, but more expensive. If you want to go there, that's a whole 'nuther discussion thread.
Cheers,
tod

External on IMac

How many externals drives or otherwise one can connect to iMac. My one USB is for I devices and one FW 800 to my external iTunes data. How can I add more.

From Wikipedia:
FireWire can connect up to 63 peripherals in a tree or daisy-chain
topology[21] (as opposed to Parallel SCSI's electrical bus topology). It
allows peer-to-peer device communication — such as communication between
a scanner and a printer — to take place without using system memory or
the CPU. FireWire also supports multiple hosts per bus. It is designed
to support plug and play but not hot swapping. The copper cable it uses
in its most common implementation can be up to 4.5 metres (15 ft) long
and is more flexible than most parallel SCSI cables. In its
six-conductor or nine-conductor variations, it can supply up to 45 watts
of power per port at up to 30 volts, allowing moderate-consumption
devices to operate without a separate power supply.

In a simple chain, 4 FW devices will work fine, though you will see performance decrease for each drive in chain. You can, in theory, chain many more, but there are a variety of issues that start at around 4 drives. You can't do this with "bus powered" drives. All drives need their own power.
USB drives generally can't be chained, but you can use a USB hub to increase drive connections. You should use one that is designed to support drives. These cost more ($50+) and require external power.

iCloud

Well I finally joined the cloud. I did some research. You can google iCloud or iCloud 101 and find all the information you will need so I won't try to explain it or answer any questions about the cloud itself. A particularly helpful spot is www.apple.com/icoud. Be sure to watch the video. A representative told me Apple's goal is to have everyone in the cloud by June of either this year or the next. I didn't listen close enough.
As far as I can tell, other than convenience, nothing has changed about my Mac, iPad or iPhone other than the mobile me apple ID and being in the cloud. All my data stayed just as I had it. I seem to have no problems at all. It says I have used 0 GB of my 5 GB allotment. More than 5 GB you have to pay. There's the rub. A nice feature is iTunes in the cloud. Anything I have ever downloaded from iTunes is available on all 3 of my devices.
I am happy with the cloud and don't foresee any problems.

Sorry for the typo in my last email about the cloud. It is www.apple.com/iCloud. Again be sure to watch the video.

Thanks Randy,
That is one I missed. I'll get right on it.
