Improvment plan on summer , suggestions ?

Hey all

I am trying to improve over this summer so I can hopefully go on a fide rated tournament next summer. My rating here on chess.com is 1468 ( I always play somewhere my rating people ). I am want to atleast improve here to rating 1800-1900( in live chess )  . What I am doing right now

Studying master games in some I just play it , in some i try to guess the moves 

Playing slow games in live chess 30 min

Analyzing games I lost ( started not long ago )

Doing tactics

Books I have ( I don't know the authors in english the books are in russian )

Kalicenko attack on the king art of attack

José Raúl Capablanca chess fundamentals ( read it once bought it so can re-read it )

A tactic book on pinning 300 problems ( had some problems in my games )

Double attack tactic book with 200 puzzles

Kotov Think like a grandmaster.

Anybody has any suggestions on a timetable , what to study , how much etc.

And 1 more thing don't suggest  silman books because I don't know where to get them here 

Edit. About openings I play as white e4

as black against e4- sicilian najdorf against d4- budapest gambit

I know the main lines of most openings

I made it to USCF 1900+ by doing a few things:

1. Analyze every position for both players in every one of my slow games.  Learn from my mistakes and realize what tactical, strategic, and psychological errors I make.
2. Read/study chess books which I find interesting (mostly tactics and general strategy books).
3. Play games with a real chess set and real opponents: there's no substitute for actual experience.
4. Start to develop an opening repertoire, but nothing too serious until over USCF 1800 since tactics, endgames, and general strategy decide more games than openings do.
5. Anything else I did for fun (bughouse, online blitz, etc.).
6. When playing in a tournament, give the game my 100%.  Take nothing for granted.  Figure out what my opponent is planning.

Good luck!

Thanks guys anybody else has any suggestions ?

Study, study, study. I'm ~1650 in live chess and I say absolute horse rubbish when people say games aren't decided by your opening repretoire. If you don't start studying that part of your game now, you won't have much of a foundation to start with when you get to 1800+. Also, it's a lot lot lot easier to play the middle game from a position you know and are comfortable with than some random position that you're probably worse in. A lot of games are decided by tactics in these lower levels. And those are important too. But having an opening repretoire allows you to get a feel for those tactics. 

Another tip is to write everything down. When you're solving tactics or strategy problems, write downn your answers and write down what you were thinking. This way, if you're wrong, you can figure out where you erred at and trying to correct that train of thinking.

Well I think an opening repretoire is useful as a general framework for your play.  I just wouldn't spend a lot of time memorizing deep lines that have little chance of occuring.  

At your level at least 50% of your time should be spent studying tactics.. most of the rest should be spent going of GM games carefully trying to understand the purpose of each and every move.  Maybe 5-10% you can spend on openings.  When you get to 1600-1700 start to incorporate more and more endgame study.  (At lower ratings you reach endgames less often).  With openings you study more and more of it the higher you get. At super GM level that's about all they do.
