I serve from time to time as a lector, and also as an Extraordinary Minister of Holy Communion (called, in Anglican Usage style, the "clerk") at our AU parish.
As Father McNamara seems to imply, I believe it is important that the lector not introduce his or her own dramatization of the readings, but instead that one read with a reverent tone that at the same time avoids being a monotone. As lector one is supposed to present the Word of the Lord, and not become the lord of the Word.
At our church, the clerk, if the deacon is not present at the liturgy, assists the priest in distribution of Holy Communion. The clerk is always dressed at least in choir dress (cassock and surplice), so the question of attire is not an issue.
On the subject of attire for assisting at Mass, I personally like to follow the practice of dressing in more or less the attire (usually coat and tie) that I would wear if I were going to meet the King (who, for Texas, would be King Juan Carlos, of course). Because in assisting at Mass, not to mention receiving Holy Communion, one does meet the King--Christ the King.
That is splendid!
But for you Anglican Use Catholics wouldn't it be the Duke (King) of Bavaria -- the rightful Jacobite claimant to the English throne? (stirring the pot...)
I like that!

We are at the feast - the Lamb's Supper!
