I traded my shiny Turtwig from Diamond to Platinum and it tends to not obey. The Turtwig was traded at level 17 before I finished my first gym badge. Currently I'm at Floroma Town and it's lv. 20 with no signs of change.
What's the quickest or easiest way to make it do what I say for good? Do I need to get the second gym badge before it get's to a certain level?
get more badges.

Doesn't matter what level it is after the trade?

It's entirely badge dependent as far as I know. Just keep it below whatever level the gym leader said was the max and you'll be fine.
You can edit it and change its original OT with the your current OT and it should obey.

Wouldn't that require external requirements? I'm using a cartridge and don't have an action replay or anything to transfer it to the computer.

once you get a certain badge traded pokemon obey you up to a certain level
once you have all 8 badges they will all obey you
Just don't grind too much ahead of the challengers' levels and you'll be fine.
