How is the station at the airport going to be modified to handle all of these extra trains?
At the moment no expansion is necessary, because for the one train per hour which comes in from Regensburg in addition to the existing S-Bahn lines, enough capacity is available. But in the context of the projected "Erdinger Ringschluss" the station will be extended to the east.
What's the Erdinger Ringschleuss? Is that an extension of the current line to the airport to connect in Erding? Seems redundant.
The "Erdinger Ringschluss" project has several goals. 1. to provide direct access to the airport from the east of Munich, the fastest growing region around Munich. 2. To make it possible to bypass the city in the north. 3. In connection with the planned re- and (partial) new construction of the line Munich - Mühldorf - Freilassing (-Salzburg), it will provide a direct access from the whole of Southeast Bavaria to the airport.
But 2 and 3 are long term projects. The construction period of phase two is estimated at 10 years from now, and for phase 3 there are no concrete perspectives for completion yet.
And even then, the result will not be comparable to the present integration of the Frankfurt airport into the rail network. It's a belated and unsatisfactory attempt to compensate for the neglect of rail integration in the planning of the airport back in the eighties.

Sorry for hijacking your thread. To sum up answers to your question:
Travel on a Bayern Ticket (€31/2) available from ticket machines or the ticket window (€2 service charge) in the airport center.
Take either the S1 or the bus to Freising, whichever will leave next
At the Freising station, verify your train at the overhead displays on the platform: For the 16:50 RE train via Plattling the terminus shown is Passau, the terminus of the connecting train from Plattling to Straubing is Neumarkt / Oberpfalz. For the 17:08 ALX train the terminus is Regensburg. You leave that train in Neufahrn(Niederbayern) +) and the terminus for your connecting RE is Straubing.
+) As Lee has pointed out, that station is not to be confused with "Neufahrn bei Freising" which you will go through when taking the S1 from the airport to Freising
