You probably should get a good service manual with pictures and procedures first. Don't try tackling a DOHC timing belt without guidance.
The hydraulic tensioner can be compressed in a vise and a pin used to hold the stem down until it is reinstalled and can then be released. Roll the crank 2 turns and then revisit you timing marks to be sure that they still line up. A straightedge across the cam bolt centers and a mirror can help you make sure that the marks are dead nuts on the horizontal before buttoning everything up.
The tensioner itself is probably OK, but you want to replace the rotating pulleys and water pump as the bearings get tired and you don't want a failure that could damage valves. You only want to have to do this job once.

The speed sensor may be a bad connection or a worn plastic gear. There is no real resistance test for the sensor, but if you turn it one revolution you should count 8 pulses on your DC voltmeter.
