Nice find! You have a Tornado Table Soccer Coin Op... also called a T20000.
It could be from the 1980's & maybe early 90's. You can get most parts on our site at this link...

Here's some tidbits re: your questions.
1. How do you remove the pins from the men to get the poles off?
You need a Pin Punch ... here are 2 that will work...

http://shop.foosball.com/superpindriver.html1.5. Can You reuse the pins or do I need new ones? Where can I find them?
You may be able to reuse some, some will come out broken, new ones are only 35cents...

New "tornado rods/poles" are pricey... and you won't be able to get CLOSE to the proper speed/play of the original tornado without new rods AND BUSHINGS that the rods come in contact with. Note these 2 items.

http://shop.foosball.com/fts-110-046.html3. Are the men re-usable or should I invest in new men, rubbers, handles, etc.? I saw some part kits on Ebay for restoring tables like I am trying to do. I would rather use the stuff I have but I dont know if its still usable.
Consider wire-brushing the men.. and you should be able to get some good life out of them. Actually some folks would suggest that the "OLDER men are bit better/more solid than some of the newest batches of Tornado men"
4. I was going to stain the handles, will this affect play (sweaty hands and such)?
Staining them will be fine for "look" of the table and will play okay for casual/recreational play. If you get some intense games/battles going on the table then you might want to look at a myriad of foos products that fooers use to "cover up the wood" and get a grip suited to their style of play and "sweat glands".

5. What should I use to keep the poles sliding smooth? Silicone? WD-40? What shouldnt I use?
The Liquid Silicon is a MUST.... note: it won't work miracles though. The rusted rods you have will more than likely have "scratched up" the surface on the bushings/bearing halves mentioned above.

The above will give you a good start. again, look at
http://parts.foosball.com for other "stuff" that is available.
7. Im used to 1 goalie, should I keep three or switch to one?
Personal preference really... there is a "1-man goalie conversion kit" in the store as well. It comes with 4 "ramps" that will glue down to the playfield, and a few other needed pieces to make the conversion.
Let's see.... your "tune up" could get pricey. You might consider doing just part of the table for starters.
... Just the Yellow side if you want to practice
... Just the 2 back yellow rods/men/bearings & the 2 back black rods/men/bearings - removing the middle 4 rods altogether and you'd have a great playing "goalie-war" table.
... If you are gung ho about the "tune up", and want to load up on LOTS of rods/parts, let me know and I can give you a break on pricing!
Drop me an email with your phone number if you want a call to discuss.
