I must admit I'm not a fan of Gina Ford ...
I read her contented little baby book before DS1 was due and thought oh, this seems like sensible advice. But literally a day or two after my baby actually arrived I threw the Gina Ford book in the bin and bought No Cry Sleep Solution on Amazon instead. The author advocates gentle parenting and is basically the complete antithesis to Gina Ford 
You may find that Gina's methods work for you and your family and that's great - maybe you'll end up with a fantastic sleeper and a great routine as a result. But I would keep an open mind because once that tiny little helpless person arrives in your life and is completely dependent on you in every way you might promptly forget all you read about routines, not carrying baby too much etc. I was fully intending on doing all the controlled crying stuff but once I heard my own baby cry instinct took over. I also found that carrying them in a sling is less stressful as they stay pretty happy, sleep easily and you can get on with all sorts of things at the same time.
Interestingly a lot of people who are into "attachment parenting" find that their babies/toddlers are actually more independent and less clingy because they feel secure that when they really need their mummy, their needs will be met immediately, whereas babies who have been left to cry can sometimes be more clingy as they're worried they won't get what they need.
Personally with our first we did a bit of a mix, not religiously attachment parenting or any particular approach. We loved slings, breastfed, he was not left to cry etc. but on the other hand, we didn't co-sleep, DS was in his own room from around 2 or 3 months old, and we did introduce routines etc.
I'm not saying don't bother with Gina Ford but I think it's good to know that if her routines and advice don't work out for you it doesn't necessarily mean you will end up with a clingy, whiny toddler who needs constant carrying
