Is it just the cover that closes quietly or the seat and the cover?

Both cover and seat are slow close

Do I absolutely need a socket wrench for this?

No you do not need a socket wrench.....

Wait! Why did the price go up almost $10? :(

Probably "Binenomics" inflation, like everything else.

is it going to fit Toto toilet model cst854?

Measure but as long as it is elongated and not round, it should be fine. Ours were exact match for American Std.
