Why were the Israelites ready to go into the promised land?

They were ready because God had brought them out, formed them into a nation, provided their leader, and substantiated everything. The tabernacle was given, and God promised to drive out the Canaanites with hornets, so all they had to do was move in and take the land.

Les explains that God had miraculously brought Israel down to Mount Sinai, given them the tabernacle, and gelled them as a nation with their leader. God had substantiated everything, so they were ready to enter the promised land. God told them He would drive out the Canaanites using hornets, and all they had to do was move in and take the land. However, Israel asked to send spies, and the spies returned with a horrible report, leading the people to weep and wail.

What had God done for Israel before they were ready to enter the promised land?

God had miraculously brought Israel out, gathered them as a nation at Mount Sinai amid fire and thunder, given them the tabernacle, and established their leader. He substantiated everything before they entered the promised land, promising to drive out the Canaanites Himself, using hornets to chase them, so Israel only had to move in.
