Regarding the ProfileView you can embed a control by placing the declartion code at the top of the ProfileView template (I hope the tags render OK after I post this):
<%@ Register src="/Portals/0/0_Utility/UserSummary.ascx" tagname="UserSummary" tagprefix="uc1" %>
note that each different control requires a unique tagprefix. it has been my experience that the control should reside withing the /Portal/
heiarchy to work properly
Then to place the control on the on the page, find the correct spot and put in somet like this:
<uc1:UserSummary ID="UserSummary1" runat="server" ForceUserID="[DNN:PROFILE:USERID]" BattleMode="false" />
you can see this in action at: http://warbeats.com/users/nfx where you will see that under the profile pic I have some badges displayed. I am also using another control on a custom tab to display the MP3 player.
notice that you can set your control properties as I am doing with ForceUserID and BattleMode
