I've got a 27" display and, at present, I need to use the whole mousepad just to get across the screen.
How can i make my mouse (Logitech MX 400) movement linear AND fast? How do i speed up the mouse with NO acceleration?

Open System Preferences > Mouse to speed up or slow down the mouse.
Go to System Preferences > Trackpad to change trackpad speed.
I don't believe acceleration is native to OSX. I have Kensington Trackball Works installed (for my kensington trackball) which has acceleration, and your Logitech Mouse center may have the same. If Logitech Mouse center is System Preferences chances are it will be under "Other".
A recently released app called SmoothMouse will do exactly what you want, and (in my opinion) works much better than the other alternative mouse drivers. It's free and available here: http://smoothmouse.com
On top of offering options for both linear and Windows-like acceleration curves, it also removes the 32ms of lag that OSX typically imposes on mouse cursors. To me, this is just as essential as changing the acceleration.
This thing is really pretty close to the holy grail - great-feeling mouse movement on OSX.
If you want to increase the speed of mouse tracking to fasted then allowed in the system preferences follow these steps:
Try MouseZoom for all the speed you want! It provides a preferences panel to increase the scaling value beyond the limit imposed by the Mouse panel.
1st set your system preferences > mouse settings then get a precision or gaming mouse that has adjustable settings.
I have a 24" imac & use a razer imperator set to maximum sensitivity because I prefer the lack of acceleration with the mouse setting.
in my experience the osx mouse settings do tend to implement acceleration in the tracking speed.
