Talei, who joined the Welsh region from Edinburgh over the summer, was instrumental in Amos' first score while No.8 Faletau created the second.
And after picking up the man of the match award, Amos was quick to credit the pair for putting him in position to strike.
"It was really good from the team and we are really pleased to get the win," said Amos.
"They were two of the easiest tries I will ever score, with a combined distance of a metre.
"The first one was great work by Netani and the second one was all Toby.
"You can see why he was a star with the British Lions. He is such a good player and brings so much to the game in attack and defence and it's really good to learn off and pick up tips from him.
"It was a good team performance and shows how far we have come that we are disappointed we didn't get the bonus point.
"But it is great for us and great to get another win here. It's such a good win, a good feeling and continues our home record in the league."
