two questions (1st is long)

Pokke Ticket plus- I beleive after beating tigrex... Not sure about on or offline
Chameleos spike- easier to get when carving from a chameleos on the high ranking quests
Commendation- reward from shen gaoren, lao, or shakalaka missions
Paw print stamp- I find them rarely from felyne chefs, but the easiest way is downloading the quest "mother of all battles". You will almost always get at least one
Hero of kikoto bio- I could almost garentee from killing tigrex
Hero of "jumbo" bio- I believe from doin the urgent quest to kill the raths to get into 6*
Fire dragonscale+- the easiest way from my point of view would have to be teostra or lunastra in high rank quests
Fire dragon powder- as I said before, high rank teostra
Sinister cloth- wow... You don't have these?! I get them all the time when sending trenya off to the volcano or desert
-----------------------------------------------------
Shen Gaoren- easiest way is to get armor with quake res and att feet... His feet will turn red... But stay on that one foot until it turns a deeper red and he collapses then attack the face... And don't forget to use the anti dragon bomb in the skull of the lao on his back... Get on a bridge and jump into his mouth after he shoots that bomb thing like the beginning movie
Teostra- use poison to get rid of his veil... It hurts alot over time... If he uses the weird sparkling move, get far away or try to get real close and hit him... He has a fire-breath move so when he does that, it would be the ideal time to attack... At 30% health, you can cut off the tail
Lunastra- follow instructions above
Kirin- fast and nimble. Attack him with a weapon that your really good with so you can actually hit him... Try to get lucky with the thunder... It's almost never the same... And try to stay on you're feet...
Lao- attack his stomach alot and when he gets near the bridge climb up... He'll either pass under you or get on his feet... When he walks by, jump on his back and lay the anti dragons... Attack his stomach for the most part and youll be happy... It's strong enough...

Tall order man... Break it down next time

Good Luck

Well all what frostflare22 realy is all that you can do but with the shen gaoren if you have really high defence when he is about to shoot just when he opens his skull mouth jump in to it you can carv it and put the anti dragon bombs on and blow him realy affective

Some additions/corrections to FrostFlare22's response:

PawPrint Stamps are also a rare 'shiny' drop after beating a felyne/melynx

Hero of Kkto Bio is obtained after beating Monoblos

Hero of Jumbo Bio is obtained after KILLING Lunastra, just completing the quest(s) isn't enough

I believe you can only get Sinister Cloth if you invest at least 300 points when you send Trenya out.

For the Sinister clothes I get them at the desert giving 300-500 points. For shen gaoren the devil slicer works fine also the djnn and crimson goat or a good dragon attrbe weapon. Keep hitting 1 leg until it goes red then continue on the same leg until it goes bright red. Repeat this to all legs. (try to get full blango)Also when you encounter a bridge clinb up to it and jump in his mouth when he is preparing the vomit ball(what I call it)and put 1 anti-dragon bomb and 1 carve. Repeat this until at area 6. At area 6 use your ballesta's (aim for the head) then use the dragonator when he's close. When your out of ammo jump down and hit him under the shell and body. By the time the time will be up and you win!
