For learning the basics of clinical examination, I second Talley+O'Connor. That said though, there is nothing like practice. Textbooks only get you so far with regards to clinical/practical skills.
Depending on keenness, you might find the 2 volumes of "An Aid to the MRCP PACES" by Banerjee et al useful. It might seem like overkill to use these for clinical school, but the books are really well written and presented, and teach you a focussed, tighter examination rather than the shotgun, do-everything-i-can-think-of approach that one is taught as a medical student. For surgery, go find a similar equivalent (MRCS final exam revision book), which should do the trick. You don't even need to reach the level the textbooks expect the readers to reach! Having understood... half, of what they want you to understand, will probably stand you in very good stead for medical school finals!
Clinical textbooks. For an intro to subjects, you can try Medicine and Surgery at a Glance. Good, gentle overview of topics. Perhaps move on to Lecture Notes in Clinical Medicine and General Surgery for more detail. If you find that lacking, Robbins', Harrison's or something along that line will keep you happy. I wouldn't rush to buy the "granddaddy" textbooks (Robbins' etc) yet. Crash Course in Pathology is probably a good idea for Path finals.
As for stuff to carry on the wards, I recommend a PDA. With a certain amount of... resourcefulness, there are many electronic references, OHCM and Washington Manuals included, which are freely available on the internet. (I personally find the Washington Manuals concentrate too much on patient management to be a good textbook for medical students. OHCM is much more useful in that regard, providing background info and pathology, etc, which can be difficult to sift out of the Washington Manuals when you're in a hurry.)
And yes, definitely buy a few textbooks at home. They cost about half of what they would here.
