Maybe you have tester on bad day or something cos most of the lighting system on 33's (my old 32 does that as well) are behaved like that, there are a mod that you can have both beams switched while high beam is activated - there are couple of threads on DIY section somewhere.
As for new suspension bits, try Nissan or Pedders or any suspension places, even give some traders on this forum a go.
Hope all it helps - obtaining a RWC is a huge pain, thankfully you're in Victoria so you only have to do once (unless you get canaried often).
