18 year old wanting to start trading

Hi,
I'm 18 and am in my second year of university. I'm studying finance/mathematics and am interested in opening up a trading account for the ASX.
Would anyone be able to suggestion what account i should open with and what software to use as a beginnner?
I'm trading $2000

ill bite, being 19 myself and having made a few trades.

few questions first:

1- how do you plan to trade? this is important! how long you planning to hold, how are you choosing stocks etc http://www.trade2win.com/media/knowledge/tim-wilcox/T2W_Trading_Plan_Template_2005.pdf
2- are you willing to lose all that $2000? not saying it'll happen but it can happen. Even a loss of 5% can be very stressful for the first trade
3- I'll be honest, its gonna be hard with such low capital. You'll be able to trade 1-4 stocks. diversification helps!
4- I'd use commsec if I were you. Take their intro offer. $500 free commission. allows you to trade without worrying about the extra costs of commission when starting
5- check out incrediblecharts its free and great for technical analysis
