A: Please use sample code below that demonstrating how to do this:

public void test_temp() {
	string mimeMsg = "paste you mime message here!";
	Stream mimeMsgStream = new MemoryStream( Encoding.ASCII.GetBytes(mimeMsg) );
	WriteTextBodies( new MimeMessage(mimeMsgStream) );
}
public void WriteTextBodies(MimeMessage msg) {
	WriteTextBodiesRecursive(msg);
}
protected void WriteTextBodiesRecursive(Entity e)  {
	if (e.Body is Multipart) {
		Multipart multipart =(Multipart) e.Body; 
		IList parts = multipart.BodyParts;

		for (int i=0; i < parts.Count; i++) {
			WriteTextBodiesRecursive( (Entity)parts[i] );
		}
	} else if (e.Body is MimeMessage) {
		WriteTextBodiesRecursive( (MimeMessage)e.Body );
	} else {
		IBody b = e.Body;
		if (b is ITextBody) {
			Console.WriteLine("-----textbody---\r\n{0}\r\n\r\n", ((ITextBody)b).Reader.ReadToEnd() );
		}
	}
}

A: You can work directly with MimeMessage structure. Following code illustrates how you can work with structured header data: 
  
  MimeMessage msg = new MimeMessage(msgStream);
  MimeField fromFld = message.Header.GetField(MimeField.From);
  if (fromFld is MailboxListField) {
      // write first email domain
      Console.WriteLine( ((MailboxListField)fromFld).MailboxList[0].Domain);
  }

  A: Yes, there is a way to change default charset (is taken from 'Content-Type' header). To do this

1. 'Content-Type' header in the body part with text body should be changed to new one
2. Current text body context should be copied into Stream with new encoding
3. Old body part body should be replaced with new one (using new Stream and new encoding) 

Following code illustrates these steps:

MimeMessage m;
// lets assume that we wanna change charset in first text part of multipart message
BodyPart bp = ((Multipart)m.Body).BodyParts[0] as BodyPart;
bp.Header.ChangeField(MimeField.ContentType, MimeField.Parse(MimeField.ContentType, "text/html; charset=koi8-r") );

string bodyContent = ((ITextBody)bp.Body).Reader.ReadToEnd();
MemoryStream bodyStream = new MemoryStream();
StreamWriter bodyStreamWr = new StreamWriter(bodyStream, bp.CurrentEncoding);
bodyStreamWr.Write(bodyContent);
bp.Body = new MemoryTextBody(bodyStream, bp.Charset);
