Also how does fast effects work? My opposition said as I was murdering one of his creatures *as a fast effect I am dealing the three damage to you before its murdered* Idk exactly how fast effects works and activated abilities all .. Can you use the abilities at any time even if it isnt your turn and the fast effects they cause? sorry I'm such a noob

Fast effects is an obsolete term that hasn't been used in years.  Now we use a system where objects put on the stack resolve last in first and one at a time.  So if a player casts a spell, you have a chance to respond to that spell with an instant or activated ability before that spell resolves. 

What your opponent is talking about is they are using an instant (or ability) to deal 3 damage before the spell, ability or combat damage has a chance to kill his creature.

OK I have another question.. the Land cards and creature cards that stat.. *tap and add a swamp or such to your mana pool* do you get to keep the mana or does it only work for that turn and then you have to discard it. and the same with the add one colorless to your pool.. I thought you got to keep them but I am not very sure ... so how does that work?

No cards let you add anything to your mana pool except for mana. No card exists that says "add a swamp to your mana pool".

You might have a card that lets you put a swamp onto the battlefield, and you can have cards that say they add 1 black mana () to your mana pool.

If you search for a swamp in your library and put it onto the battlefield, then you can use it as normal. If you add 1 black mana to your mana pool (like by tapping a Swamp for mana), then you lose that mana unless you spend it by the end of the current phase or step.
