you say you are looking to perfect trading executions and generally good trading books
to answer your first question no book will teach you that, that comes with experience. Some books may show you from the authors/trader point of view how they would enter a trade but you will find thats unique to each individual and style of trading
as for trading books again really down to your style, many short term traders use indicator some look at price action, others timing some use level II (time and sales to get a feeling of short-term movement) chart patterns fib ratios the list goes on and on, read up on all the resources trade2win as its free and may well point you in the right direction before you go and spend money unnecessarily
