1st complete flight, departure and crz good BUT landing................

Hi guys its an amazing aircraft really realistic my departure was perfect crz was fun and went well approach and landing was very hard i have over 2700 flight hours with flight sim and this was my 1st flight ever with the 737 let me tell you i was busy.It started off that i seemed to be coming in to fast i did not feel like my spoilers worked at all anyway in the mean time the fmc gave me a few mssgs stating that i had no vref set and that my Ils nav was wrong when i was 100% sure of it, i did put it in nav 1. End result hard landing, visual since my ils did not connect and auto brake and reverse thrust went well to slow me down until the end of the runway. Thank god there was no traffic i did a very early morning flight to avoid it.I know i need to figure out the fmc for arrival but it seems so complicated then again thats how i felt about takeoff.Any remarks or suggestions???
