Gina Ford has no childcare qualifications nor is she a mother. She also threatened to sue mumsnet and could have got us shut down. (She is however good at selling books.)
That's all you need to know IMO when deciding how much credence to give her ideas!
Specifically about putting a baby in a nursery. Well Pickles77 I think you'll be a great mum as your mum instincts are questioning that one already!
The government recommends keeping your baby close - in the same room as you in fact, until they're 6 months old, as it helps protect against SIDS (cot death).
Your baby learns to regulated their breathing by being close enough to you to hear your breathing and the CO2 from your breath own helps.
Routines suit some people and not others. What irks me about Gina Ford's books is that she claims that if you don't follow her routines that you're making a rod for your own back. Not so. For some people (like us for example) going with the flow and following our babies cues about when he was hungry / tired worked much better than spending hours trying to get him to go to sleep because the clock said so!
Also if you follow Gina Ford's routines to the letter it makes establishing breastfeeding very difficult. Babies often cluster feed in the evenings for example, and her routines do not allow for this.
I know some people like the routines, but personally I would steer cleer!
