Hi Kellie_shakur,
I was in the same place you are...I wasn't able to shower until my husband got home from work. But all that changed with EASY. Now I can workout, eat breakfast, and shower all during her first nap...sometimes I can even get some housework done! It made such a big difference in my life!
As for starting the routine, I would recommend looking at her normal waking time. The book recommends 7 am but my baby likes to wake at 6:30am (which ironically was the time I used to always wake up for work before having her!). I think that starting at a time they are used to getting up will make it a bit easier--just stay consistent with that time (ie not letting her sleep late) and make sure that it works for you (for example, if you are going back to work and need to be out of the house at 8, a wake time of 7:30 or 8 may not work out well).
I would definitely start with the 3 hour EASY. She may need to move to a 3.5 hour EASY (there are sample schedules under the FAQ section of the EASY forum) within a few weeks but you can handle that later or change based on her lead/cues. There is also a board for Colic that you may want to look at (I have no experience with that).
Other tips:
Definitely keep a log. That was very helpful for me and I still keep one now. It helps me identify when she needs changes to her schedule.
Explore the boards here. There is good information from all the moms. The FAQ boards have great info on sample schedules, common problems, appropriate awake times for certain ages. Also reading others posts can be helpful and make you feel like you are not alone.
Also after a week or so, reread the book. I found a lot of info that I had missed while trying to get the big picture!
Also, please give the techniques at least 1 week to work. The first week was horrible for us. My daughter (7 weeks at the time) fought so hard against EASY. But after that first week things started going so much better. She was a happier, well rested baby and I was a happy mommy! Even my family noticed a difference in her! So stick with it. It is called EASY but it is hard work!
Good luck
