I get wack focusing in AF all the time, I just retry and usually it comes good on the second or third go. Never occurred to me to blame the lens per se, although certain lenses do seem to give the AF more bother than others - the 55-300 I found particularly capricious.

When you say '50% of the shots I have taken are not in focus' - surely that would be 100% if the problem is 'front focussing' (the technical issue du jour). (Presuming you're talking about shots taken under similar conditions).
Why not post some samples, it's pretty hard to comment otherwise!

While only a small proportion of most people's shots will need dramatic recovery, and hopefully the WB isn't grossly out on too many of them once you have processed a few shots in RAW out of necessity, it's so second nature you may as well do 'em all in RAW, even if you apply a fairly modest tone curve adjustment (all RAW edits can be saved as presets, which speeds things up a lot).
So can someone enlighten me (excuse the pun), if I am not changing the white balance when I apply a White Balance Adjustment in software to an out-of-camera Jpeg file, what am I changing?
Raw files have not had while balance set. They are tagged with whatever the camera's setting was, (either that which was manually set or via auto-white-balance), but the actual data has not been changed. This allows one to set any colour temperature and white balance one wishes after the fact with no image degradation. It should be understood that once the file has been converted from the linear space and has had a gamma curve applied (such as in a JPG) white balance can no longer be properly done.
Because Raw files contain a wider gamut of color, the white balance can be corrected without any noticeable loss in detail. Using Raw converters such as the Photoshop Camera Raw plug-in is easier and produces better result. On the other hand, the white balance of JPEG files can be easily corrected without much noticeable loss in detail.
