dear friend,
are u preparing 4 jee, aieee in future?
keeping i e irodov is good but you'll land up in confusion as many problems are way beyond the thinking ,the questions are good but you have to think out of book tricks to solve them  fully.
i would say resnik halliday is a must u must use it while solving irodov. concepts will become better with resnik-halliday.
for organic morrison is good for reference, but keep a side book for practicing reactions mechanisms etc. u can have schaums 3000 problem in organic chem, other like I.l. finars' problem in chemistry etc.
there is no prob in keeping books but you should make the table to go through them regularly.
						

							
Dear Sandeep
There is no problem in taking all the books but there is no need of it and these books are not written exclusively on the pattern of JEE. Just refer maximum two books for a subject otherwise it will kill your time. arihant books are well written for JEE.
 
All the best.
