Thank you carlston, very useful answer.I was struggling to decide between an online website to learn and practice (drivingtheory4all.co.uk/) or the 2 books you have mentioned, and I think I will go for the 2 books (hopefully I will buy them on amazon or ebay at cheaper price).
You need to book your LGV theory tests on the official government website:
The part 1a multiple choice test costs £26, and the part 1b hazard perception test costs £11.
There is often a 4 week wait for an available test slot, so you might want to book now. Also, consider booking a second set of tests in case you fail the first time, maybe a week or two after the first test dates. You can always cancel tests and get a full refund if you cancel at least 3 working days before the test date.
