How can I calculate with the help of the numbers in the TF2 wiki how long does it take, in seconds, for any class to:
The one specific scenario I need help with is the minimum time between sapping a building and starting shooting it with your gun.
It's not necessary. Although the minimum amount you can add to the Steam Wallet is $5/5€, the remaining money past the purchase price will stay in your Steam Wallet.
You can use it as part of the payment the next time you buy a game from Steam.
Normally weapon stats only apply when the weapon is active, however there are a few exceptions to this, the pain train being just one example. The wearer gets both of the weapons benefits regardless of whether or not the weapon is active:
Weapons effects which take place without the weapon being active will be followed with "on wearer", like in the above example. These effects will also appear under the "Current on-wearer attributes" header on the character load out page:

According to an interesting forum post describing the advantage of the degreaser, the default switch time is 0.67 seconds.
As far as I know only the Degreaser (65% faster, 0.67(1-0.65) = 0.2345 seconds) and Reserve Shooter (15% faster, 0.67(1-0.15) = 0.5695 seconds) can affect this, besides the weapon-specific limitations as mentioned in Toomai's answer. Also of course the Half-Zatoichi is 'honorbound' and has a switch time as long as it takes you to get a kill!
