Brand new advice please

Firstly, thank-you for the opportunity to post on this site. I have read as much as time allows and already have learned from you all.

As a busy Mom to 4 small children I am looking for a hobby for myself (I have always had an interest in photography) as well as a way to possibly earn income down the road. I have so many questions!
1) What camera is appropriate for learning and for use possibly for income? My wish would be to one day be priviledged to take pictures for families, especially infants and children in client's homes/location. The Canon Rebel seems to be the camera of choice for me thus far???
2) I am unable to attend a full time college course. Are courses necessary? Would part time 3 hour classes at the closest Henrys help? Is it crazy to think I can self teach through years of trial and error?
3) What would be the basic kit I should purchase? Camera, lenses, lighting, on and on... I find all the research I have tried to do I am still left with a big ? Money at the moment is a huge factor. We are willing and happy to invest as much as we can, but I want those purchases to be valid and worthwhile. What would you suggest as a basic started kit that would suit for now and in the future? From what I understand you purchase the basic camera and then there is a whole lot more to buy. :-)
4) Which computer editing program is best to invest in... that is something I have not researched at all as of yet. Is a separate computer beneficial... a lap top?

Thank-you to all that lend some advice. I am so thrilled I found this site so between diaper changes and children's lessons I will reading with interest.
