There is a guide here that tells you most everything you need to now about choosing and installing ubuntu.
More then likely all drivers that you need are going to be installed when you install ubuntu, there is usually not a need to install any extra except possibly for your video card and wifi connection.
Video card drivers if you need to install one can usually be installed from additional drivers that comes with ubuntu, also the same with some broadcom wifi cards.
If you have any issues after installation then start a new question about that specific issue.
If you are dual booting in 14.04, wubi has no official support any more so do a normal dual boot and not a wubi install.
