Do you already have wireless internet in your home? If so, you will need to do absolutely nothing.
Really as long as you have access to internet you don't have to do anything anyway...you just pick your book from the website and it downloads it onto your e-reader, just like that. Easy.
Hubby had a Kindle, it was cool. We all liked it. It is broke. If I had to choose I would go with the new Nook "Color" it goes for @$250. The older version of the Nook comes in 2 different varieties...one is $150 and the other is $199, they have different capabilities but I think both are worth the $ and would be sufficient.
Which ever way you go, I am sure your daughter is gonna love it! Great gift!
~Oh, I think I am partial to the Nook because I have gotten a huge gift certificate to Barnes & Noble every year for the last 10 years as a Christmas gift from my in-laws and this would work well with that AND I have never heard of the Literati...gonna go look into it!
