Thinking of playing SnGs seriously... What should I do to prepare?

[djg40]

What sort of software programs should I have, how should I keep track of my finishes, etc? As of right now, I just plan on keeping it in Excel. Is that not enough? I mean, are there programs tailored to the more serious SnGer?

Also, how many Buy-ins should I have in my Bankroll?

If these questions are asked, and I am sure they are (but damned if I know how to use the search feature to actually limit the results to what I want), then just point me to the appropriate threads.

Thanks!
Dan
