You should get proper legal representation. Hopefully the solicitor you have picked does plenty of criminal law. Depending on your solicitor's experience, he/she may well be able to handle the matter themselves without a barrister. You need a competent advocate in the court, not necessarily an expensive one (a QC/SC really sounds like overkill unless you're rolling in cash). Feel free to ask your solicitor what his/her experience in these sorts of matters is. If your solicitor can't answer your questions satisfactorily, find another one. Your State's law society may be able to help you in this regard.
In terms of answering questions from your prospective employer, you MUST answer questions truthfully as a lie that is later found out will justify terminating your employment. However, you are not obliged to volunteer information. So, for example, if you are asked about convictions you need not volunteer that you have been charged.
Finally, as we hear regularly these days, it's pretty easy to kill someone with 1 punch if they fall and hit their head. If you get through this one OK, walk away next time if you can.
Cheers
