If you need a simple introduction to Talmud I recommend the book of Rav Shach's the Avi Ezri which combines simple, straight logic with depth
When I was in yeshiva there were two kinds of books around "Deep Lumdus" Deep learning and "Easy Lumdus." The easy learning. The easy learning one were things you could learn and understand without having to have gone through the whole subject in depth. These were things that I would pick up and learn on Friday nights. [But it still gave you a good idea of the depths of the subject.]
The hard Lumdus is what it sounds like "hard." That is Reb Chaim [Soloveitchik], Baruch Ber, Shimon Shkop. Rav Shach combines these two things. Easy to understand without having to know all the sugia in depth while at the same time introducing you to the depth. [Yaakov Abuchatzeira also wrote a very good book of what you could call "easy Lumdus." An excellent book.]
