I ordered a set from the finescale thread-Click2Detail. They took quite a while to arrive (6 weeks to 2 months or so?) but the website says to expect several weeks. I am quite pleased with the drop tanks and ordnance I got. It's all in semi clear plastic so it's tough to make out the surface details, but they look good to me. I have no experience or knowledge of the Kokoda ones.
There are some 1/350 decals out there, generally you get a whole airwing with a set and they are cruise specific. Starfighter decals makes some and I thought I saw some on GMM a while back for an Enterprise cruise.
