weekly study plan

I don't think that it is a good idea to devise an in-advance plan. I suspect that it is best, at any one time, to use your recent playing and studying experiences as a guide as to what to do next. However, if you really insist on a plan, I suppose that you might go for Build Up Your Chess 1, Boost Your Chess 1, Chess Evolution 1, and Revision & Exam 1. The Yusupov series of books seems to be pretty demanding, so I suggest that you look carefully at available samples and reviews before buying.

Perhaps it is worthwhile to note the somewhat casual attitude that was adopted with regard to the order of topics:

"... This book is the first volume in a series of manuals designed for players who are building the foundations of their chess knowledge. The reader will receive the necessary basic knowledge in six areas of the game - tactics, positional play, strategy, the calculation of variations, the opening and the endgame. ... To make the book entertaining and varied, I have mixed up these different areas, ..." - GM Artur Yusupov

If you decide that you are satisfied with these books, you may eventually want to go for the others: Build 2, Boost 2, Evolution 2, Build 3, Boost 3, Evolution 3.

have heard Jeremy silmans how to reassess your chess is an excellent book study endgames too

Watch a lot of top tournaments........and read books.

Of course, playing in tournaments will yield the quickest results though. 

Your course of study should really be based on improving your weaknesses. The Yusupov series mentioned by @kindaspongey (who looks a lot like a pawn) is great for all phases of the game. Another possibility is Khmelnitsky's "Chess Quiz", which presents a number of positions and rates your ability in 12 areas of play. If you go through it faithfully, it will show what your weak areas are. 

If you don't want to spend many hours on that book to find your weak areas, there is a piece of sage advice that someone once gave me: study the areas that are least interesting to you, because those are surely the areas you've paid the least attention to and are therefore the weakest in.

Best of luck in your quest for chess improvement!

Highly recommend Yasser Seirawan's Play Winning Chess series
