I know exactly what you mean. There just aren't enough hours in the day!!! I hadn't put out any new designs in months. But since last week I started trying to stick with a weekly schedule. Mon, Tues and fri work on orders and the rest of the days work on designs. That didn't quite work, so now I'm trying mon,wed,fri (orders) and tue, thur (designs). So far so good. Maybe you can implement some sort of schedule, where at least once a week you work solely on new designs, photos, listing, organization, etc.
What I also did recently was update my shipping times adding a few extra days. Hadn't had any complaints so far and I feel much less stressed.
As far as accounting; I HIGHLY recommend Outright. It's a life saver! All my etsy and paypal stuff goes in there and it organizes everything. Then all I have to do is add in a few receipts at the end of the month. I think you can also link your bank and cc, if you have a separate biz account.
Betsi is another great tool. I used to spend hours sometimes even days updating all my listings, now it takes me 3 minutes on average.
