I'll leave it to others to comment on lens choice other than to say that the 18-135 and the 10-24 is my basic travel lens combination But as far as the grip is concerned, leave the grip and buy the Neewer Portable dual battery charger. It charges two batteries at once, weighs almost nothing, and cost less than $11 on Amazon.
