There were 70 appointed to help Moses.
It doesn't have a "name", it was called a "staff". Moses was a shepherd, and shepherds used staffs to help them with their duties.
Jethro took Moses in as a guest when Moses had to flee Egypt. He gave his daughter Zipporah to Moses in marriage (Exodus ch.2). Later, Jethro brought Moses' family to him in the wilderness (Exodus ch.18). At that time, he suggested to Moses the idea of appointing judges/officers for the Israelites (ibid).

The Sanhedrin is not a location, but rather a group of people, a council of sorts. It was kind of like a religious court in that time. It was first formed by Moses in the wilderness when his father-in-law suggested that he elect elders from among the people to help him judge the peoples problems.
The tabernacle was built according to the instructions given by God to Moses, with the help of skilled craftsmen and workers chosen by Moses. It was constructed by the Israelites during their time in the wilderness as a place of worship and to house the Ark of the Covenant.

The Bible doesn't actually say take your problems to your elders, but the elders are the shepherds of the flock - 1Pet 5:2 and people are encouraged to submit themselves to their elders - 1Pet 5:5. If you are sick James writes call for the elders of the church -James 5:14 So it seem a reasonable thing to take your problems to your elders for help.
Possibly a city manager.
