True, you can't go wrong with most Meguiars stuff. Except their tire shine. Stay away from the purple bottle!
If you want the actual Honda branded stuff this is all they have I think. From College Hills Honda.

2 soaps I like from Chemical Guys:
Citrus Wash: Really strong soap for when the car is very dirty

Glossworks Soap: For when you have already detailed and waxed the car. This stuff does not strip wax. The Citrus wash mixed very strong will. This is a great maintenance soap.

For the interior you can always get the Honda stuff but I like this stuff from Einszett lately. It definitely has an industrial serious cleaning has gone on sort of smell.

If the interior is not too dirty and you just want to get the dust off this stuff is the best though. Its almost all I use for interiors. It also has UV inhibitors to protect everything from the sun.
If you only want to buy one thing get this stuff. 303 Aerospace Protectant.

303 Also make a great fabric and vinyl cleaner. They have a protectant also if your stuff isn't dirty yet.

EDIT: I almost forgot.... as far as clothes go I am no help there. Wear what you like? I guess. Hahahah, I think that must be a typo though.
