Minecraft adding orespawn mod into hexxit mod?

I'm not at all great with computers, but I recently downloaded a mod for minecraft called Hexxit
which is great because there are so many things you could do.
Most recently, I've been wanting to add more mods to my hexxit mod
I have followed a video:

(loud video)
And I did just as they said, but while the mod folder for the orespawn is in the hexxit mod folder and I try to open my hexxit (through technic)
It would load the mojang screen, but after that it would show a black screen and not the minecraft home screen.
I was thinking that maybe they're not compatible, but I see people playing with these two mods together.
Could it be that one may be outdated?
when I go into hexxit's options menu on technic It says my "build" is on 1.0.10
and when I play the hexxit minecraft it says I have the 1.5.2 version.
Sorry if this isn't enough information!

Can these games run well on these computer specs?

I was wondering if the following games can run well on these system specs on at least normal settings at a decent FPS rate (stable 30 FPS or above). Games:
-Minecraft
-Team fortress 2
-Garry's mod
-Blockland
Specs:
System: AMD A4-5300 3.40GHz Dual-Core | AMD A55 Chipset | 8GB DDR3 | 1TB HDD | Genuine Windows 8 64-bit
Graphics: Radeon HD 7480D GPU | 24X Dual-Layer Drive | Audio: 8 Channel | Gigabit LAN | Keyboard and Mouse with Scroll Wheel
Expansion Bays/Slots Total(Free): 4(3) Ext. 5.25" | 6(5) Int. 3.5" / 2.5" | 1(0) PCI | 1(1) PCI-E x1 | 1(1) PCI-E x16 | 2(1) DIMM 240P
Connectivity: 1ea. PS/2 Mouse/Keyboard | 6x USB 2.0 | 1x RJ-45 Network Ethernet 10/100/1000 | 802.11b/g/n Wireless | Audio | 1x VGA | 1x HDMI

If you do not know how well all of the games can run, it's fine. If you don't know what you are talking about, I kindly ask you to refuse from answering- I need this computer badly.
All help is appreciated.

Will mods break all of my Minecraft worlds?

I want to start installing mods, but I read somewhere that outdated or broken mods may result in losing the world. However, I just plan to use mods on one of my worlds. So, if one world gets lost, will all of my worlds get lost? Should I back my worlds up just in case?

Give me a modded minecraft Version folder?

I keep trying to install the World Edit and toomanyitems mods, but I keep failing and the game won't even open, the launcher just closes and re-opens itself. Can you guys mod a file for me and give me the link to download?

Is there any Minecraft mods that add a follower/companion (like a human)?

Already tried Orespawn, but I couldn't stand the freaking termites so I uninstalled it.

I'd like a follower to just keep me company in single player. A good pet mod would be great too but I'd rather have a human friend. I have Millenaire and Sim-u-Kraft (on separate profiles) so please mention if any mods would conflict with those.

I'm also looking for good mods in general (for 1.6.4 preferably) as my Minecraft doesn't have very many mods. If you know of any good shaderpacks that don't lag that would be good too, thanks.

But if I can get a bigger bang for my buck tell me

Can I install Direct X on this video card?

I have this stupid video card that can't play even the simplest games in full FPS (ex. Minecraft)
I really want to get Garry's Mod which requires Direct x 11 or something. I checked if Garry's Mod is compatible with this pc and it said I meet all requirements except my video card is the problem and it doesn't support direct x.

Any suggestion? Please Help!
