What's your time line? This looks to me to be at least a 1-2 year, possibly 3 year project - have to allow time for living. Need the OEM manual for the 1000 and 1100. Did you get all the body parts from the previous owner?
Since this is your first major Reno of a motorcycle, mine was 8 years ago with an '85 GW Limited Edition fuel injected model that was on the road. This is my long term retirement project and I'm still working on it. I also have a 2014 CanAm Spyder. I would suggest if I may, a way forward to get a feel for what you have.
I would not strip the bike and start from the ground up. You should be able to clean it up and get it turning over as is. Once you determine what you have, then go for the "Full Monty".
Take lots of pictures, note wiring connections, clean all connectors and replace. Take off anything that looks like it doesn't belong, noticed a couple of items. If there are wire splices, remove-discard, go back to the original installation.
Make sure the engine is free to turn.
Prove the electrical system works such that you can check for spark. Here's a wiring diagram:
You will have to refurbish the carbs to get it going, or at least disassemble, clean and reinstall. May be enough to get a cough or two out of it. A small ultrasonic cleaning unit is good for this. This is a 3L unit:
The throttle and clutch cables can be made by yourself, kits are on the web as well as info on how to make these.
Purchase a small endoscope that you can use to view the inside of the cylinders.
You will need a set of vacuum gauges.
Check the orientation of the carbs, in this I mean which carb is the base carb that you use to do a carb sync. The 1100 is carb #3, just for info a 1200 carb setup uses #4 as the base.
If you are going to do the swing arm bearings, you will need a special tool. I use a Park Tool FR-6, get at any bicycle shop, and inexpensive. Think it works on the 1100 as well, not too sure about the 1000:
Once you clean up what is there, it will not look so daunting.
Make a list of what you may need such as brake and master cylinder kits and determine availability.
A few thoughts. Hope this helps.
Good Luck. Cheers
