I was wondering: Which, if any, of Ryouga's belongings (clothes, cooking
implements, gas burner) would have survived sitting at the bottom of the
Spring of Drowned Black Piglet for three years, and still be in somewhat
serviceable condition? Also, could someone tell me if Ryouga started
wearing that bandanna before or after he visited Jyusenkyo?

He was shown in a flashback scene wearing something different when he
took the plunge. (Vol. 2 part 8 in the original manga, part 2 of trade
paperback 2 in the Viz translation). A plain headband (no spots). So
one would presume he picked up the bandannas we know afterwards.
Not sure about the answer to your first question.

        Actually, as of the Saotome's arrival at the Tendo residence, only
one month had passed since Jusenkyo... therefore, at the end of the
series... roughly only a year has passed for Ryouga's stuff at the bottom,
so some of it  still ought to be okay...
