Barney, your constant bumping leads me to see you as very attention seeking. You bump your threads constantly, and disregard help that is given to you. Sorry, but that is how I think you have been acting.
As for reading your original post, Modloader and MC patcher are completely different things. Toomanyitems has nothing to do with texture pack, it is a mod/cheat that lazy people or builders use if they can't be bothered gathering materials, or a tool people use for quick and organised mod spotlights to be put on youtube.
Are you using mods, or just a texture pack? If you aren't using mods (Toomanyitems hardly counts, but you may want to uninstall that to be certain) I have no idea. The biggest resolution texture pack I've ever used is 256 or something, so I'm not sure in general.
