Yes shim the lever . It keeps you from breaking the tit off the brake light switch. If you don't shim it , just be very careful when re-installing and you'll be fine. Replace the tbw with the SE tbw because it eliminates the green connector.you could just cut the connector out and solder the wires together. Either way get rid of the green connector.
Not sure about if you need extended clutch or brake line but you'll have plenty of wire to work with.
