Hi, doing good, how about you ? 
Yes, most definitely. Last Longer, Yippee Ky Yay and Get some are the Holy trinity, you should put 5 points in all 3, always, no exceptions. I’m ready already is nice until you have access to Get some, but afterwards, it becomes nearly useless.
Absolutely no. So many builds don’t need Money shot, but Gunzerking is a must
Or to put it another way, I’ve made lots of builds without Money shot…but never without Get Some
All of these work yeah
The reason Grog/Harold is so popular is because its easy to play and easy to setup and you don’t have much to think about…but that doesn’t mean its the only option.
Hoarder builds are awesome IMO, but don’t feel limited to anarchists: every gun that is not semi-auto, that consumes 1 ammo per shot and that is fairly powerful can work.
I love using the Lyuda with a hoarder. Don’t worry about the low ammo capacity of snipers, You’ll never dip below 80 bullets out of 132.
Here are a few great combos for Hoarder builds:
Dual Slow hands
Dual Kittens
Grog/Lyuda
Dual Rubi
Slow hand/heartbreaker
Slow Hand/Blockhead
Grog/Longbow
Grog/Anarchist
Grog/Topneaa
Dual topneaa (yes, you can totally do a pure RL build
)
Moxxi/CC
Slow hand/Butcher
Kitten/Ogre
Moxxi/Teeth of Terra
… see how this is going ? … I could carry on. Just try what you like 
Other options Include Sljm’s Pimpslapper (Grog/Pimpernel)
You can also do good stuff with a bit of Brawn, which allows you to use more powerful guns because you’re not limited to Moxxi guns in your off-hand, but you have to be a much smarter player and/or use guns that are effective at a longer range
Dual Pimp works very well here
Swordsplosion too
This is also the right time to try those ludicrous guns like the Chopper 
You can also do Melee: Just get a pair of Rapiers, a Might of the Seraph and carry a bladed Grog to swap to when you need it, Spec in Fistful of Hurt and wear a Leg. Berserker COM.
Tediore chuckers are pretty fun too. A Devastator, War Dog or Legendary Hoarder COM and a pair of Tediore SMGs and you’re good.
…And there is of course a Deputy setup as an option
If any of these strike your fancy, I can come up with a build and loadout for you
