Taking it out of the front end is easy if that's all you're after. In account.aspx you'll need to remove these 2 lines:
259 by default:
Code:
<td align="center" valign="top"><b><asp:Label ID="accountaspx40" runat="server" Text="(!account.aspx.40!)"></asp:Label></b></td>
276 by default:
Code:
<td align="center" valign="top"><%#" " + GetShippingStatus(Convert.ToInt32(DataBinder.Eval(Container.DataItem, "OrderNumber").ToString()), DataBinder.Eval(Container.DataItem, "ShippedOn").ToString(), DataBinder.Eval(Container.DataItem, "ShippedVIA").ToString(), DataBinder.Eval(Container.DataItem, "ShippingTrackingNumber").ToString(), DataBinder.Eval(Container.DataItem, "TransactionState").ToString(), DataBinder.Eval(Container.DataItem, "DownloadEMailSentOn").ToString()) + " "%></td>
That'll stop it from displaying. Taking that info out of the DB entirely (if that's what you're after) would take changes all over.
