Triple Booting with Ubuntu, Adding Ubuntu to a dual boot config Options

[Clayman1000x]

I asked this question at another forum but have got no answers so I am posting here also.
"I am currently dual booting XP Pro and Win7 Ultimate, all updated and running fine. I want to add Ubuntu 11.10 to the system, I'm fairly new to Linux but not a newbie. Now, I have done this before BUT, I installed Ubuntu inside either XP or 7 (don't quite remember which). When booting up I would get a bootup screen with about 4 to 6 options for booting into Ubuntu, 2 options for some type of repair and an option to boot into Windows, if I accept the last option (boot into windows), I get another boot screen asking for XP or Win 7, I would like this to be the same after I reinstall Ubuntu to it's own partition and this time I want to partition an area of my boot drive for Ubuntu. I currently run a 85g partition for XP (my main OS), a 45g partition for Win 7 and will add a new 40g partition on the storage partition, (currently 338gb) for Ubuntu and the rest is storage space, I have plenty of space for this. I am currently moving all the stuff in the storage part to another drive.

I hope I explained well what I am trying to do:

The real question is what do I need to be prepared for and what steps do I do if the boot screen doesn't give me what I need. I would like this to go smoothly and I already have Ubuntu 11.04 on my other pc and am getting used to the Unity interface, not as bad as what I have been reading IMO. I would love any suggestions someone might have.
The reason I am doing all this is because my Biostar 6100-M9 MB gave out on me and I replaced it with an Asus A8N-VM, 939 socket board so I lost my installs but nothing important, I never keep important stuff (thank god for live cd's and gparted) on my boot partitions, that is what my storage is for."
By the way, when I am done and everything is working fine I am going to backup the OS partitions with Macrium Reflect and store them on the other drive.

Allright, I bit the bullet and installed 11.10 64bit. I had made an "unallocated" partition of 50gb of a 338.8gb partition using windows hoping the install would grab that 50gb and install there. But what it did was add both "unallocated sections together again and install to the whole 338.8gb. Now I need to shrink this but can't find gparted in the system settings page. I also can't get internet going because it doesn't seem to find the USB Netgear wireless dongle. I tried using "MiniTool Partition Wizard Home Edition" to shrink the partition but it won't do it.
My main problem now is getting the wireless adapter to work, but I would need to find the drivers in windows and stick them on a flash drive to upload to Ubuntu. After that I can down;oad the packages including gparted to shrink the Ubuntu Partition. Help!
