hi there sweetie,
Just want to affirm that you are doing a great job. It is a mighty transition to being a first time mommy, so I encourage you to be gentle with yourself and know you are doing the very best with your baby.
After following the EASY routine for a year, I can truly say that this routine does a wonderful job of getting life into a predictable rhythm for mom and baby. I think with your LO being so young, it may just take a little time to get her on any kind of routine. A lot of folks suggest not getting too rigid with it until 2 months or so, though it is good to get into good habits and teaching shh/pat.
You could maybe try to shorten the A time down to 1 hour, if possible, and see if she gives you a longer nap. If it ends up being short, then you'll want to shorten the following A time a little. But really hun, since she is sleeping so much, I would go with her cues and just try to get as many naps as possible. And you need to get some rest too!
