i'm not an expert as to what textbook to use, but study tips depend on your individual learning style.
what i did for prelim chem nearing to the exam was to get a cardboard A3 sheet and write everything i had learned onto it (really summarized so i only used the one paper with small writing). when you spend time summarizing really well and condense-like, you'll remember it more because you put the time into doing it.
i also can't stress enough the importance pf doing practice questions - i know i should have done more.
