How to create a script to unmount a disk not permanently without typing the admin password?

Question

Hello everybody!
My problem is the following: I have  a macbook Pro with a Bootcamp partition, which is also virtualized by Virtualbox. I managed to make it work following different online guides that share all the main little side issue: if I don't want to dismount forever your Bootcamp disk from the running OS X, I have to use some "sudo" commands that requires me to type my admin password. In order to do so, I have to open the Terminal, type the string, type the password and then, only then, I can use the virtualized version. Well, since these ones are computer machines, born to work on repetitive and tedious processes, I'd like to automate that.
I have a little script, which doesn't work, that I'm showing you (Let's say I wrote it to make it clear to you what I would like the machine to do):
do shell script "sudo chmod 777 /dev/disk0s4"
tell application "Finder"
    if exists "BOOTCAMP" then
  --Eject BOOTCAMP Volume if Mounted
          do shell script "sudo umount -f /Volumes/BOOTCAMP"
    end if
end tell
--Launch Virtual Machine
do shell script "vboxmanage startvm BtCmp-Win7"
What I'm now asking you is the following:
(a) is there a way to make it work without using my admin passaword? (... I really think the answer is no... )
(b) if the answer to (a) is no: is there a way to make a little window pop up to ask me to write the admin password and make everything work?
(c) I would like the disk to be remounted automatically once I Quit the VirtualBox application, how could I do that?
Well, I hope some kind hearted one can help me
