I just flew to and from Modlin airport on Wizzair last week, and the shuttle/train was very easy. At Modlin you get on the shuttle bus which takes you in 8 minutes to the Modlin train station. There you catch the direct train which goes to all Warsaw stations (Wschodnia, Centralna, etc.). The train ride takes about 48 minutes. You can check train times on the Polish rail site: http://rozklad-pkp.pl/bin/query.exe/en?ld=s4&OK#focus
The combined ticket shuttle+train costs 12 PLN on the shuttle. If you book a Wizzair flight you can pre-book the combined ticket for 5 Euros. There are also various options at Modlin airport for a bus to Warsaw for 33 PLN, and taxis, etc.
