Hi lenny!
There's no easy answer to that, there's many versions of dayz and each one will most likely require its own fixes.
With the latest vanilla versions for instance, you won't be able to do much without unlocking the SP button again, wich requires some config knowledge. The FSM file handling the player spawn will also prevent you from playing solo, so you'll have to figure out how to edit it.
And from there the real work begins : you will spend days (weeks, months!) testing it, looking for broken mechanics (there
will be plenty!), stress-testing others that usually depends on the server or weren't designed to be saved & reloaded. That alone will be the most time-consuming task; the placing of IAs and vehicles isn't so hard, eventhough there are some limitations you have to work with.
The whole process is extremely complex, empirical and different depending on the version you work on - so don't expect to find any tutorials on that. The best way to learn is to take (a lot of) time to look into an already existing SP release, compare it with the vanilla version and see what was edited. You could try with a simple one like
DaiZy+_v[Rz0].
Last but not least, you should spend as much time as you can on Armaholic or the BIforums : there isn't a single technical question that hasn't been brought up there. Make yourself a collection of tutorials and read them carefully, even if they do not seem directly related to what you are looking for - it will always be usefull! You might also find usefull tips on opendayz.net, it's probably the best source for dayz-related stuff.
Don't hesitate to throw questions here; if I have come across the same problem or have time for it, I might be able to help, or at least point you to the right direction. ;)
