The Vault Hunter's Relic only drops the chances of white item drops by 5% and then splits that 5% between the green and blue drops. so say if the odds of drops are:
No drop:40%, white:30%, green:15%, blue:10%, purple:5%, orange:Only on named & bosses (and often about 1% or less there) OR 3 borderlands symbols on a slot machine (about a 1 in 5,000 chance)
The Vault Hunters Relic would only make that:
No drop:40%, white:25%, green:18%, blue:12%, purple:5%, orange:Only on named & bosses (and often about 1% or less there) OR 3 borderlands symbols on a slot machine (about a 1 in 5,000 chance)
assuming those numbers were accurate (the orange is pretty close but the others I am mearly speculating) then even if it were modded to be a 30% better chance (thus eliminating white drops all together) it would still only be about: None:40%, White:0%, Green:38%, Blue:17%, Purple:5%, Orange:special.
No modding of %'s will make the Vault Hunters Relic really worth wearing once others become an option. Better to wear a relic that works to improve your strengths (such as an elemental boost on a siren or a brand-specific relic that helps boost your best weapon) or compensate for a weakness (+shield capacity or max health if you find yourself dying too easily).
No, Just like many other quests in the game, there are two possible rewards and you have to pick which one to go with while locking out the other one for that playthrough.
The only difference is this quest doesn't say return x to person a for one reward or person b for a different reward. You just have to make a choice and that's the choice you're stuck with for that playthrough.

After you complete the all the side quests linked with Clan War: Zafords vs Hodunks and choose to go with the Zafords and you kill all the Hodunks, anytime you go back to the dust and go to the exit where Lynchwood is the Hodunks will respawn and you can farm that way. Good Luck getting the SMG.
(The exit to Lynchwood from The Dust is a train station)
