get some nylon washers for the underside between the basin and the tap backnut if its not tightening, and yes be careful not to overtighten or "SNAP" go the nuts.(¾ top hats if its the bath taps) I dont know why they dont supply them with the taps, a question I have asked myself a hundred times when I go to tighten on the basin taps, followed by a run to B&Q usually! lol If you can get hold of some brass backnuts it would be in your interests.

There are no markings on the taps because thats just the style you have, taps are mostly all of the same type these days(hot used to have a "floating" jumper inside and cold didn't, or was that the other way round... anyhow they are mostly all of the fixed type now)so it's up to you what side you put them on.

they stop the taps moving! lol

also when removing taps it can make things a bit easier, as well as holding the nut further from the rim to get yer tools on. you could use a regular nylon washer instead, top hat washers are just the "done thing".
