Where does Parris want to see gold candlesticks?
The answer to this is that he wants the gold candlesticks to be on his altar. He thinks that it would be better for their church if they had gold candlesticks on there.
We find this out when John Proctor is arguing with Rev. Parris. He is saying that Parris is too concerned with having nice stuff -- that he wants the community to pay for all these luxuries. Proctor points out that there were pewter candlesticks when Parris came, but Parris nagged and nagged until people bought him gold ones.
This shows how concerned Parris is with the reputation of his church and how much he wants people to show him proper (in his opinion) respect.
On the lectern at the church. It's a particular source of agitation for John Proctor, who feels that his and other members of the congregation's money is being wasted by their preacher. He states that it hurts his faith to see "my money glaring at his elbows" when questioned by Reverend Hale about his spotty church attendance.
It is also a window into the character of Parris, who seems a little dimwitted, actually, and caught up in the trappings of privilege that go along with his job, and his position in Salem society.
