Abbyy's OCR engine is probably the best there is, but as for scans, I usually prefer Adobe Acrobat's Clearscan mode over Abbyy's compression (I've been using only older 11 & 12 Abbyy versions though), because one thousand page textual book (A5 or A4) will usually be turned into a suitable 20-40 MB sized Clearscan pdf file (depending on the letter size and number of graphs/tables/pictures therein), also pretty easily flipped through on my older eink readers, whereas Abbyy's pdf scans (OCR text layer behind the scanned image) will not be as smooth to flip through i.e. they would need newer readers with stronger processors and more memory.

As for Q1, Yes, you can use ABBYY to re-compress your existing PDFs, or you can use some pdf editor to decompress pdf pages beforehand (to recreate original images), and then to feed those images to ABBYY, if that would be quicker.
