S.L.
I'm not trying to brag here, but I have a lot of experience with digiscrapping, so I think I can steer you right.
There are a few ways you can do this. One is photobooks. That's Snapfish, Shutterfly, etc. You upload your photos, you arrange them according to their layouts, and then you order their book. This is what I recommend for my mom, since she doesn't really care about creating unique, artistic pages.
You can also go to places like Heritage Makers and do something similar to Shutterfly, only you get to add more embellishments. These are very expensive, at ~$80 for a 20-page book. And you have to have memberships or something, and different levels of membership have different access to graphics.
Then there's what I do. Since you're already an experienced paper scrapper, you may not want the limitations of photo books or the price of Heritage Makers. You already know how to put a page together. So now you just need to learn how to use a graphics program, get your graphics, and start scrapping! This method offers you the most flexibility, but can also be time-consuming. Just like paper layouts.
Digital Scrapbook Place is a great place to start. I started there. They have great freebies, reasonably priced graphics, and a great community. There are "contests" to help you get started on the right foot, tutorials, and even classes.
I'm going to give you a few links to look at. It can be overwhelming at first, but I would be more than happy to help you get into this wonderful hobby! I have helped lots of people online or in person get their graphics downloaded and organized, and helped them to learn how to save their pages in the right format and size for printing and sharing on the web.
Also, I'm a frugal person, so I know all the ways to do this as cheaply as possible. There's even a free program that you can download that is similar to Photoshop. I wrote a tutorial for Digital Scrapbook Place on how to use this program to create your first scrapbook page, so I'd be happy to share that wit you, as well.
Here are my links, and please feel free to send me a private message for more info:
First, a link to Digital Scrapbook Place's user galleries. These are scrapbook pages made by DSP's members (free membership, and you get a free kit by signing up. No spam, either) You can see that digital styles might be a bit different than you're used to, but you can make your pages look just like your paper ones if you'd like.

Second, a link to a tutorial called Digital Scrapbooking 101

When you're done with your pages, you can either have them printed as a hardbound book (such as a photobook from Shutterfly--you'd just upload your pages and choose a full-page spread) or as individual 12x12 prints that you slide into a regular post-bound scrapbook. That might be the perfect choice for you, since you can mix your paper and digital layouts in the same book. A LOT of digiscrappers "refuse to choose" between paper and digital, and some even do hybrid pages that use both!!!
