Cool :-)
Now you have your machine booting, you need to either buy a Kickstart 2 chip, or Amiga Forever which contains a legal ROM image. Softkicking without one of these isn't allowed. The ROM chip would be the better option as it would remove the need to softkick altogether.
Alternatively, now you can boot, you could make some Workbench 1.3 disks and install 1.3 to the hard disk instead of 2.05, then it will boot 1.3 without needing to softkick.
