How to tweak hierarchial SQL queries?

As an Oracle newbie, I've recently discovered the START WITH... CONNECT BY clauses in SQL. It is really neat, but.....

1. Is there any way to affect the order in which "siblings" are returned? For example, we have a parent-child table containing locations. I'd like to see this result from a query:

Arizona

   Phoenix
   Tempe
Arkansas

   Fayetteville
   Little Rock
   Texarkana
   ...

I can't get the "states" and "cities" to come back in alphabetical order.

2. Is there a way to sneak past the prohibition against joins with CONNECT BY?

Thanks in advance for your help
