How much memory does your PC have total?

Allocate less RAM, try 4GB

see if this issue applies to you
 

I don't know of any pack that already includes those mods. 
You could use Tekkit Legends or most any 1.7.10 modpack, and add:
https://minecraft.curseforge.com/projects/archimedes-ships/files/2207285
and
https://minecraft.curseforge.com/projects/worldedit/files/2309699
to your mods folder 
I highly recommend you read https://minecraft.curseforge.com/projects/worldedit if you plan on making much use of it. There are other things you can download to make it more useful. 
 
 

Have a look at the 1.7.10 pack, http://www.technicpack.net/modpack/the-1710-pack.453902
It is a large 1.7.10 kitchen-sink pack. 

So have you figured out how I fix this? I highly appreciate that you are helping me with this.

Install this Java http://cdn.lemonmc.com/jre-8u25-windows-x64.exe
Then allocate more ram to the launcher. 

Don't allocate more than 4GB of ram, and make sure it's using your Nvidia GPU and not the Intel one. Check your video settings too in-game and try turning off Fancy graphics and reduce the chunk view distance. 

Close the launcher
run this http://tk.iamtrue.net/clearJavaEnvVars.bat
and try again

Version 1.11 is available on modpack settings page as an option, if that was your question. As for mods moving to 1.11, that is up to the individual modders to decide if and when. 

everything is in a folder called modpack, the the bin, config, and mods folders should not be in a subfolder. 

format your dropbox link according to https://www.circlecraft.info/hosts/
I forget to tell you that the zip needs to be named modpack.zip 
it should contain
mods -- should have all your mods
confg --your config files, adjusted as you like them. 
bin -- should contain forge universal renamed to modpack.jar and nothing else. 
 
 

rename the file and get rid of the space
The Nomad.zip is not OK
thenomad.zip is
You'll need make a new dropbox link, and increment you pack version number. 
Also, you have a lot of extra stuff in there. 

Attachments don't work here, use patebin. As for pluggins, you may want to try Thermos http://cyberdynecc.github.io/Thermos/install instead of Cauldron
Many bukkit pluggins work with it. 
Use build 57

did you rename the forge universal in your server's  clientpack /bin folder to modpack.jar? (If Windows is hiding file extensions, either unhide them or just name it modpack)

in your /world folder there is another folder called HardCore Questing, remove it and relaunch. 

servers.dat
 

If you are referring to the Mods tab you see on some packs' pages, I *think* you need Solder for that. 

You want Forge Essentials for 1.7.10, assuming your running a Forge server. 
https://minecraft.curseforge.com/projects/forge-essentials-74735/files?filter-game-version=2020709689%3A4449
Not bukkit. 
And don't make a /pluggins folder, they just get dumped into /mods 
 

Install this  http://cdn.lemonmc.com/jre-8u25-windows-x64.exe
 
and try again. 

No problem. Work's been busy for me lately. I sometimes have time in the morning and occasionally in the evening.  With luck I'll be on later tonight  
There's a new pair of regular players too, say hi to Sentinel and IceFaery if you see them. 

If it's 1.8 or later for some reason 
the whole permissions thing confuses me. If you don't want people using it, don't release it.
on that ftb list, red checks mean click and read why the answer is "no"

Pastebin your log
Though I suspect you have Windows 10
if so, try java 8u25 x 64
http://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html#jre-8u25-oth-JPR

No, the second person will be rejected by Mojang's Auth server. If you want two people playing online at the same time, you will need two paid accounts.
