Workfow wise I download, cull then just go through my shots one by one or edit one and copy and paste develop settings to do a batch. I have lens profile corrections applied on import. From there I'l then do merges (panorama or hdr if thats ehat I shot for) then open in photoshop if complex cloning is needed, then back to lightroom and in the develop module I'll crop, set black and white point, contrast, highlights and shadows adjustment if needed along with clarity and vibrance, sharpen and noise reduction. From there I'll do CA and back to the top and work on any others that need adjusting or fine tuning then apply local corrections grads and doging and burning.
