Minecraft: Not Enough Items and Fossils and Archaeology installation?

I've seen many let's play vids on Youtube with the Fossils and Archaeology mod. They all have the Not Enough Items mod installed with it. How do I do this? I have scoured the internet trying to find out how but only com up with tutorials on to install just one of the mods, not both of them together. I have tried installing them myself but to no avail. Once it showed that NEI was active but when I opened my inventory, nothing was there. I must be doing something wrong.

Will this Retina Macbook Pro run Minecraft at 60+ fps?

I'm thinking about getting a Macbook Pro Retina display with these main specs;

Intel Core i5
2.6GHz
512GB Storage
8GB RAM (Up to 16GB)

Running Mavericks (Mac OS 10.9)

I was wondering if Minecraft could run at around 60+ fps on Max, Medium, and Low video settings without ANY mods or Java modifications?

An answer is much appreciated.

What are Minecraft class files?

I'm trying to install Dr. Zhark's Mo'creatures mod. I went to the Installing Mods website on minecraft.gamepedia.com, and I'm on step 9:

"Open the class files from the mod with an archiver such as WinRAR or 7-Zip and copy-paste the files into 1.6.4_Modded.jar. Do not close the archiver yet."

But I have no idea what class files are or where to find them.

How to add mods (and use them) in Minecraft Cracked?

I have Minecraft SP Cracked (1.5.2) and i want to know how to add mods and don't forget how to use them too. Also it would help if you give me a couple of links to mods. It would mean a lot to me.

Minecraft 1.7.2 Timber and portal gun mod?

I'm looking to install Timber (or an equivalent) and a portal gun mod for minecraft 1.7.2. If someone could link me to a page where I can install these mods, and also let me know how to install them, that would be great. I've read in some places that you need forge or something along those lines when using these mods so if I need it I'll get it. I already have optifine and TMI installed so if you know that there will be some issues with that then let me know, otherwise I can find out myself.

My Minecraft Launcher isn't working? - 1

I'm using the launcher given on minecraft.net to play, but it won't work. I tried to install a few mods like smart moving and mo creatures along with the morphing mod, and i noticed that it doesn't reach the title screen. I thought that it was just crashing, but no, its not even crashing, I've had a crash screen before. Anyways, the launcher just acts normal as if it would play, but then it just closes and re-opens. (Note: i had mods before this happened and it worked just fine.) I tried to remove the mods i tried to install leaving the mods i already had, but it still wouldnt work. I tried a few suggestions, ( like logging out and logging back in) but that didn't work. I Updated Java like 10 mminutes ago, which i tried after doing, that didn't work. I just wanted to know if there was a way to fix it.

8GB 1600MHz DDR3L SDRAM
128GB PCIe-based Flash Storage

Please don't recommend some other laptop or something I just want to know.
