I don't know where the trouble is, so i'll tell you all:
first press ctrl+shift+c to bring up the cheat window.
type testingcheatsenabled true and press enter
shift click the mailbox and you can select a lot of things, but you need force npc now.
if you select force npc you can select which one, and they'll come.
the grim reaper will appear somewhere in the house, but you cant talk to him and he will leave immediately.
warning: i have never tried these myself but i heard the repo-man wil take a LOT of items (like 20) and the social worker will take away your children even if they have all green bars.

Well there is no cheat all you have to do is make your Sims do their homework. If you have Sims 2 Seasons you have your sim drink apple juice before they do their homework. It will help them do it faster.
No sorry there is no motive cheat on the sims pets. Edit: There is none for Sims Pets, but there is one for Sims 2 Pets. It is 'maxMotives', also type in 'help' in the Sims 2. That will give you a large list of cheats. Note: Must be in Sims 2, or it will not work.
i need help as well
You have to age it into a child first. Testingcheatsenabled true can help with the age transition cheat.
if press control+shift+c then type help there's a list. and 'testingcheatsenabled true' gets you more.
