Deano,
problems with the lens can be corrected (not 100%) in PP but it is important thet the original image have the much information posible.
JPG will eliminate a lot of parameters or information in the image which will be lost.
If you are worried to start taken shots in raw or nef only what you can do is use more memory card but shot on dual mode nef/Jpg
Allways save in a separate file your nef files because even if they are bad today in the future when you developed more understanding of PP you will be able to recuperate a lot of images.
When you open the processed image from ACR in PS work in tiff format and save your copy in tiff as well.
While you work on your tiff image
do the following:
Go to layers and duplicate the layer so you do all the adjustments on the duplicate layer (image) and do not apset the original file.
Only do your adjustments in "new adjustment layer" wher you will adjust firts the levels and then work in curves.
In this way you do not destroy the original information and you can delete the layers if you are not happy with the result.
I recomend to you to get a copy of Photoshop for Nature Photographers by Ellen Anon and Tim Gray. It is an excellent book and easy to follow.
Please do not hesitate in asking questions, that it is why we are in this forum to help each other
