yes, but it's more complicated than adding weight. Google moment of inertia (wikipedia probably has what you want). I'm sure it would be nice to break it down into xxx grams, but that just isn't how it works.
Nope, but I swear I'm quicker and more nimble going uphill with no bottles or saddle bag... especially on a long mountain climb.....
It's nice having someone hand you drinks while you are pedalling!
