If you're planning on boxing long term, take a hard look at IS Boxer.
You get a lot of bang for your buck.

Auto FTL, without messing with macros or scripts.
Mouse Repeater and Repeater Regions.
Click Bars.
Flexible Mapped Keys - Toggles, Slave or Master actions, etc.
Send Next Click - Ground Target AoE's.

If you're not likely to box much, or are comfortable with scripting (or willing to learn), look at HKN.
It gets you most of those features, and is free.



As far as what Blizz doesn't know.
You'll probably be fine.

But you might not be; if anyone reports you, a GM will check the names on the accounts, and if they're different you've just lost both accounts (banned, not suspended).
