I can't think of any way to use gold properly. It is quite weak when used for tools or armour, and because of its rarity, I'd rather not use it for stuff like that. I'm also not really into decoration, so just a gold wall won't really be the answer I'm looking for! Is gold just useless or is there something that only can be made with gold?

I can confirm that PlayerPoints works with BossShop, as it states here: 
There isn't a BEST shop plugin, while BossShop currently is one of the really good ones. PlayerPoints is kind of like an economy plugin anyways.
I'm assuming you're using a command block with a summon command. Basically. you need to specify the data tag on the command to give the mob the desired attributes. For attack damage, that would look something like this:
summon Giant ~ ~1 ~ {Attributes:[{Name:generic.attackDamage,Base:10}]}
Here attackDamage is measured in half hearts, so this command would span a giant zombie which does 5 hearts of damage per hit.
See also: this page with some more information about attributes.
To get a command block, type:
/give <username> minecraft:command_block

I use my gold for enchanted items that I don't use a lot like silk touch shovels for when I need grass blocks. Gold tools mine faster than any other tool and also have the highest chance of good enchantments.
Other than that If you use minecarts you might use most of your gold for powered rails. those take 6 golden ingots to craft but you get 6 of them every time you craft them.
You can also combine gold and melons to get potions of healing. which can be helpfull if you take a lot of damage. (I have dispensers all around my base which can heal me whenever I need to)
Having clocks around your base can help you if your base is underground
Other items that you are able to craft using gold are golden apples, these give you a nice buff but cost quite a lot. also the golden carrots that can be used for breeding rabbits, taming horses or making nightvision potions.
