Both the Cross and the baptismal font are very central to Lutheran theology. I would venture to say that any congregation that does not have these as focal points are trying to diminish their lutheran (or sacramental) identity.
Ideally the baptismal font should be at the entrance of the sanctuary so it is the first thing people see/encounter as they enter for worship. Since this is our entrance into the Christian community (though, I'm aware, not for all people these days), and it is something we remember daily (Luther said we should remember our baptism daily). Also, funeral rite center on God's promises made in baptism. Because of both of those reasons it should be the first thing encountered before Worship and the last thing when leaving.
Also the font should ALWAYS have water in it (it would be a bonus if it is flowing water). This reminds us of the daily reality of our baptism and the constant presence of God's promises made in baptism.
I like your sanctuary Cableguy. However, wouldn't you have a "table" instead of an "altar?" Liturgically, an altar is something that is up against a way and a table is something that is push away from the wall and has access from all sides. I think this distinction is key since it puts a different emphasis on what communion is. Catholics have Altars since the Eucharist represents the atoneing sacrifice made over again. Lutherans have moved (or tried to) toward having tables since we celebrate the Eucharist (which means "thanksgiving") as a gathering of believers. This tradition is closer to the earliest traditions of the church (ie. that we get from the Didache). I really do think it would be beneficial in our day and age (lack of "guilt" these days) to get way from the atoning sacrifice ("poor me...I'm a sinner") view of communion and move toward the celebratory emphasis of the Eucharist to celebrate what God has already done (and continues to do) for us!!
Just a thought!
