lossless = every bit of information of the video can be reproduced.
Say, you make a video and then export it as wmv, put it back to the editor, export it as wmv and repeat - and even on high quality settings, you'd lose information and the video would get blurry and pixelated.
On the other hand, if you do the same using lossless codec, all the information to recreate the ORIGINAL picture is in there and can be used by the editor. Even if you repeat, if the editor and codec are good, you will always get the same thing.
Also, usually the editors are optimized for using lossless sources (or rather, the lossless codecs always feed them the full info they need. Some lossy codecs might feed them "enough" - but not all of them and "not always"!) - they work with them better and faster. Using lossy codecs is usually slower and can break virtually anytime for no reason.
Also, even with lossless, you might improve the preview with using RAM preview - Shift + B upon a section. Or look it up in Vegas Help ;x
