Welcome

First, gather and organize your photos.  This may be the most time consuming part of your project.  To save time just organize for one book at a time.  For instance, if you are starting with a baby book, just gather and organize all of your baby photos.  Scrapbooks are not for every picture you've ever taken (that's what albums are for).  Search through the photos and pick the best and cutest pictures to use.  You'll know them when you see them.  If you don't have the time to get all of your photos in order, just make piles of pictures: Photos you want to use and those you don't.  Then just keep narrowing down until you have the ones you plan on using and then put those in chronological order.  Keep some of the "maybes" around in case you need some as filler pictures.

Next, gather the supplies you will need.  This can be very simple or very elaborate, it's up to you!  Basic supplies include: Card stock paper, patterned paper, adhesives, a binder, page protectors and some decorations (die-cuts or stickers).  A customized theme kit will give you everything you really NEED, except a trimmer.  If this is your first scrapbook I would recommend buying a basic supplies kit as well.  I can't say enough about how important it is to have a trimmer.  You can get away with not having all kinds of scissors, circle and oval cutters, pens and punches, etc., but a trimmer is a must!!  Once you've got the basics and decide you want to do more elaborate things you can move on to the more specialized equipment.

Next, start laying out pages.  I usually do a few at a time before I actually glue anything, but I have also laid out the entire book before making anything permanent.  You will be able to get a feel for when a "section" is complete and can probably be set.  If you feel you have no creative ability at all, there are hundreds of layout ideas on the internet.    Everyone's style is different, so find one that you like and begin.
