A really good cheat that I know is one where you can raise all of your sims needs and skill (job promotion thingies) and personality points. Just put ctrl+shift+c in the neighborhood you picked and type in boolprop testingcheatsenabled true (pay attn. to the spaces and spelling) and enter a house and you can raise all of their bars, you can also shift+click (after doing the cheat above) the mailbox and click on make friends for me and your sim will be friends with everyone in the neighborhood. There are also 2 money cheatas I know, first enter a lot with a family in it then do ctrl+shift+cand type in motherlode in the little box. This will make your sim richer by $50,000 simoleons. For the other one do the same until the cheat box comes up and type in kaching for your sim or sims to be $1,000 simoleons richer.
Hoped this helped!
