smsf general q?

Hello all,

I am bit raw on the SMSF idea and after a few quick answers.

I've been looking at the esuper.com.au site for reference and would like to know the following.
1)Can I open an SMSF Bank account, attach a commsec share trading account and trade my superfunds online the same as I do now with a standard bank account??
2) If this is possible, am I bound to purchase any shares in particular ie asx 200 etc?

Thanks in advance
