You use it to gain experience points in creative mode, you can only get it in creative mode, but then you can switch to survival with cheats.

If you are the server owner (or can get the owners to change game mode or just yours) you can switch it to creative mode in the server conf file or by command in game by and op. otherwise a server in survival mode is staying in survival mode.
Yes. Time is the same in creative or survival.
with the "creative" button.
Impossible. If you are in Creative Mode, you can not craft!!
You can in Survival Mode, but not Creative Mode because in Creative, you have all the blocks and such you need, but in Survival, you don't get everything when you start. Hope the helped!
You can use a crafting table in creative mode just as you would use it in survival mode.
I would recommend you get the SinglePlayer Commands mod for Minecraft. It is very easy to install so don't worry about a difficult setup.
276 in survival mode. 322 in creative mode.
Play it in survival mode or creative mode. Don't press the multiplayer mode.
