Tivo/Direct TV- Any opinions, pros or cons?

Yes, as you all know, I'm a newbie, but all your help and e-mails have
been wonderful.

I just ordered direct TV and Tivo to be installed in my new home next
month, and I was wondering what you all though of those two services,
and what to do to maximize their efficiency.

Thanks for any help!
