The pack is simply an improvement in the quality of the already existing textures and shapes of the elements in the game, so do not expect any big change or difference with the base game. It focuses on bringing higher resolution textures, and brighter colors, and although it also changes the lighting and the shadows in the game, there are more specific mods to improve the shadows and the lighting of the game. Look into shader mods if that's what you are looking for. All the Faithful 32x pack does is making the game look nicer. It is not a mod, and as such, it does not introduce any new element of gameplay to the base game. All the mods you are currently running should still work fine after installing this set of textures. The author of the pack maintains a list of which mods are compatible with the pack, and which ones aren't. Keep an eye on the list to make sure the resource pack is completely compatible with the mods you have currently installed.
