Concerning Advice of Going Blonde

I am deciding on going blonde! I am a natural red head and have recently went dark. Being a brunette looks good but i want a change.

To go blonde i will have to strip off my dark hair dye and my natural colour, is this right?
I just want to make sure that doing this, would be a good decision. I don't want my hair to go orange, frizzy or look dead. I am getting it done professionally, will there be any problems? Will this turn out okay?
And also, i am not exactly going blonde, more like a honey brown.

thanks
