Wheat is best gotten from growing it in a farm plot. There are a few places on our island in K-11 that you can get seeds, but easiest is probably to just ask someone. I have well over 100 wheat seeds, and I’m sure others have extra too. Or you could just ask me for wheat as I have plenty of that too (though it does spoil, it lasts much longer than wild vegetables).
Honey I have heard is in k10, though haven’t personally seen it (or looked). I got all my honey from k9 (I think, the first lawless k zone that is north of k11). There were nodes everywhere and so I stocked up, though my stash is almost depleted now. It took about 20 honey (probably less) to tame a high level bear with the double tame event, so plan accordingly.
For taming elephants, @Taramil has set up a taming pen in J11. For Bears there are two decent options. K10 has a few taming pens open for everyone (not built by us). K14 has a number of taming pens and traps built by other (primarily I think to capture wolves back when k14 was infested with wolves).
