Put the SWF files from each mod into your [game folder]\Mods\$INIT$ folder. Edit Mods.txt in that folder and add the filenames of the SWF files. For each mod, there's also a settings file which you need to put into your [game folder]\Settings folder.
edit: for moreclothing, you also need to put the "moreclothingmods" into the ½INIT$ folder.
The setting that Deltavoid mentions is called "enableinloaderediting" which you can find in the animtoolsVxxsettings.txt. If you set it to 1, it will allow you to edit positions in game. I myself prefer to have it set to 0 and just keep a copy of the SWF file in the game folder, so that I don't have to edit the settings file each time I want to edit/create a position.
