Check whether you've setup your SMTP settings correctly via the host menu - that should resolve your #1 issue. Look at various posts on this forum for SMTP settings which should help you get on your way with regards to this problem.

With regards to #2 issue, see this thread for a resolution - http://www.dotnetnuke.com/Community/Forums/tabid/795/forumid/30/threadid/55164/scope/posts/threadpage/6/Default.aspx

So can you walk me thru accessing the stored procedures to modify the code.

CREATE PROCEDURE {databaseOwner}{objectQualifier}UpdateFeedbackStatus
 @ModuleID int,
 @FeedbackID int,
 @Status int
AS
IF @Status = 4
 DELETE {databaseOwner}[{objectQualifier}Feedback] WHERE FeedbackID = @FeedbackID and ModuleID = @ModuleID
ELSE
 UPDATE {databaseOwner}[{objectQualifier}Feedback]
 SET    Status = @Status
 WHERE FeedbackID = @FeedbackID and ModuleID = @ModuleID
GO

If you modify this stored procedure as follows, it would allow you to update the status of any feedback submitted (ie similar to what was the case prior to 4.4.3).

CREATE PROCEDURE {databaseOwner}{objectQualifier}UpdateFeedbackStatus
 @ModuleID int,
 @FeedbackID int,
 @Status int
AS
IF @Status = 4
 DELETE {databaseOwner}[{objectQualifier}Feedback] WHERE FeedbackID = @FeedbackID

ELSE
 UPDATE {databaseOwner}[{objectQualifier}Feedback]
 SET    Status = @Status
 WHERE FeedbackID = @FeedbackID
