Oh please don't stress
I was exactly the same at the beginning I used to have a mini panic attack at pick up / drop off time too incase a parent was not happy.
Now I am much more chilled and don't think, sleep, eat, breathe childminding all the time
Once you have been doing it a while it will get easier - its like any job.
As for the toys - just build up gradually look at car boots charity shops ask around friends to see if they are having a sort out, freecycle is good also.
Hope you have a good day today xx
