Upgrading a Shimano dinosaur?

My daughter has a ten year old MTB with Shimano 18 speed gearing. We like the frame and want to keep it, but upgrade the gearing.

So I've bought a Shimano "Megarange" screw-on freewheel. This has a biggest sprocket of 34T. The existing biggest sprocket is 28 teeth.

Will I need to replace the existing derailiur? Will any long derailiur do, SRAM, or Shimano?

Will any 7 speed shifter be a suitable replacement for the existing 6 speed one?

    more info needed as to what the other bits of the gearing system are. ie the mech.

    you will need a new chain whatever.
