Lightroom affecting image quality?

[oO Stevie Oo]

Howdy

I've noticed a few things times with lightroom (3.4) recently that pictures that start out crystal clear on the camera have noise on them or degraded quality after processing,
Could someone please advise what you can change in lightrooms develop interface without affecting picture quality or creating noise?
I very rarely adjust exposure and thought the rest are fine when shooting in RAW but I think I may have been wrong lol

Example below... that picture is crystal clear (@ the nose of the car which is what I was going for lol) and noise free on the camera but after processing, its lost some of the sharpness and gained some noise :/

Help please
Cheers

Cheers all
(sorry for the long time no reply lol, been busy)
I've slightly changed the way I process now and tried different thing with the NR feature etc,
Does this image seem to have noise?
It doesn't to me but im on an LCD TV as a monitor so not exactly great for processing :/

I don't know any other way to get photos with processing out of lightroom :/
