Nostalrius Begins - Quality wow vanilla realm (1.12)

Do I take Efficency over Improved Hunter's Mark?

For example If im only level 35 , would 2 points of Improve Hunter's Mark even make a single DPS difference?
Or what about Improved Serpent Sting, if im using like r5( 210 dmg), would 2% even make a single DPS difference?

Finally...is Aimed Shot even worth the talent point in vanilla pvp since it doesnt even reduce healing by 50%, and is affected by pushback and taking a ton of time to set up? Or should I just go Auto/Multi/SSting/Auto/Arcane(and repeat without even having AS in my rotation?

If you're only level 35 you should be putting points in frenzy to make your pet OP :^)

Increasing the extra attack power from hunters mark by 6% at that level would make almost 0 difference. 2 points in efficiency would obviously not make a big difference either, but I'd go with that over IHM. The serpent sting talent is shit. Definitely get Aimed Shot, it might be hard to use in some pvp situations where you have to keep moving but the damage it can do is huge (blow up casters in 1 burst with crits). It gets much easier to use with scatter shot + FD traps though. Putting it in your rotation at a low level can be hard since you need a slow weapon to make up for its cast time, but I'd recommend speccing BM+MM until 60 and picking up Aimed at 51 anyway.
