no, too many items mod is a separate mod which allows you to get any block or item from your inventory as if you were in creative mode. there are also various other features of the mod, like switch from survival to creative etc.
Well, you don't need it but for easier loading, it is recommended.
No. I use that mod and I don't have mod loader.
Lots of mods do not need forge, big ones such as: OptiFine Too many items and Better Sprint (all i know of)
In minecraft beta, there is creative mod what allows you to get all items.
You can't you need to find it in a stronghold :) Not true you can get it using tooo many items :)
if you mean little numbers as in single player comands to get wool you cant you need to many items
Yes i need a loader
Boot Loader Grab is the bootstrap loader that you need for Ubuntu 14.04.
In your minecraft.jar file, (which you need winRAR or 7-Zip to open with), delete the META-INF file.
yes they do! and too many items will give you the rings babies eggs for spawning MCA (because they are not villagers they need different eggs) and tombstone for the dead ones or that will die eventually
I don't really know but you might need a mod-loader or mabye see tutorials on how to get the pixelmon mod without the mod-loader.So really im not an expert
Yes, but first you need modloader to run X-RAY and modloader seperates Too many items and X-ray from crashing to each other.
Pressure Plates, and indeed all redstone items, have not yet been introduced into minecraft PE. This'll come in a future update.
