Can't help you much with the incense holder thing, but I can answer your other question.

shibaraku: for some time, awhile
e.g. shibaraku omachi kudasai. (Please wait for a while)
- This can be said by the store person to the customer whether in person or over the phone.
shibaraku deshita ne. (It has been a while..{since I last saw you})
- Said between friends.

ohisashiburi: after a long while/absense
e.g. ohisashiburi desu ne. (It has been ages since I last you, isn't it?)
- Basically, we use this phrase to greet someone that we have not met for a long time.
