You should have variety on your moves. Only because houndoom is Dark/Fire doesn't mean it should have only dark and fire moves. In fact, if you have two moves of the same type, most of the times you'll use just one.
If you have more types, you can hit more things.

Also some of these items I can get and some can't: So I only have limited access to them.

Garr helped me with these two pokemons:
Houndoom item hold focus sash:

nasty plot
dark pulse

Item hold left over

I am assuming that you have no idea what significance natures, EVs, and IVs have in a battle. Even in the Battle Tower one bad battle can ruin a perfect streak. You really need to get something better out of it. Dark Azelf should get you covered but it's really beneficial to learn these things yourself.
