Autocad 2000 used to have a problem where if you used the Lengthen command, it would randomly crash when you are working on that drawing. It wouldn't crash when using the Lengthen command but at any other time later on. Not sure if it's the same in LT2000 but I'd imagine it is.
As JStephen says...
One of the first things I did in 2005 was turn off background plotting. It takes much longer than plotting normally. Just turn it off and forget it's there, it's a useless feature.
PS Turn off your capslock.
Delete any layer filters that are in your drawing, they have a hugh impact in the drawing size in 2005 and will probably cause the same problem in 2005LT.
Just print your drawing the same as you normally do but click on PRINT TO FILE before clicking on PLOT. This way you divert the plot to a file instead of the plotter. Remember to set all the fields as if you were actually plotting as the imaging company can't modify the plt file before it's sent...
Thunderchunkydan. I'd suggest upgrading your graphics. Integrated graphics controllers aren't designed for handling drawings of your size. even getting a cheap 128MB graphics card (like a 9800pro or 6200) would make a hugh difference. If you're working on drawings that size on a regular basis...

64Meg is huge for an Autocad drawing. Even extremely detailed 3D drawings shouldn't be that big (at least 99% of teh time, there's always exceptions)
Purge the hell out of it and delete any stray non referenced objects in the drawing (like blank attributes that have been disasociated with...
Sometimes when doing 3D the osnap marker will display at the current elevation rather than at the point you're snapping to.
If you're snapping to an endpoint at 10,10,10 and your elevation is set to 0, the osnap marker will display at 10,10,0 but it will pick up the point at 10,10,10. Not sure...
Assuming it's Windows XP you're working on, disable the automatic restart funstion. It'll cause windows to restart anytime there's an error.
Control Panel -> System -> Advanced -> Startup and Recovery -> Click on "Settings" -> Untick "Automatically Restart"
Use Designdenter (ctrl+2). Browse to the folder and select the drawing you want. If you're looking for a specific block but don't know what drawing it is in, this is about the fastest way of doing it.
You could also try this
Tools -> Customise -> Keyboard
From this dialog box you can define any keyboard shortcuts that you want. This is probably what Exxit is referring to.
By the way, this is for Acad 2005, but I'm fairly sure it's roughly the same for older versions as well.
