Like others who come here that are going to install their own irrigation systems I'd recommend that you start with http://www.irrigationtutorials.com/ which will give you good all around advice.
Besides that I'd recommend:
1. Have the largest POC (point of connection) that you can; greatest pressure with greatest GPM makes for more leeway when designing zones. Test it! Don't assume what you think you have.
2. Design head-to-head (or as close as possible). This will eliminate thinly watered areas that will be prone to weeds and other problems.
3. Don't mix sprinkler types; i.e. spray pop-ups with rotors.
4. Choose a zone sprinkler that has good matching precipitation and don't max out all the zones. Leaves room in case you add hardscape, shed, etc. at a later time which WILL be on your honey-do list in the future.
5. Automate; don't go manually activated. You'll save money and time.
6. Design with winterizing in mind; right materials at proper depths, PVB/BF that is easily drained/blown out, attachment for blowing out system, etc.
There's plenty more but I'll leave it to some of the other guys/gals for now.
