No in fact they are not. Halo Reach takes place about 4-5 months prior to the events in ODST. At which point the SMG was created and people at UNSC started equipping ODST units with them. The only thing that is remotely close is the fuel rod gun, gravity hammer, pistol (minus the silencer), and assault rifle.
you need halo 3 ODST to access the halo reach multiplayer beta
I would say if you don't own reach then don't buy it. From what I hear, halo 4 is going to be similar to Halo 3.
Buy halo odst

No, firefight was not introduced until Halo ODST which was made after Halo 3. Only Halo ODST and Reach currently support it. Halo 4 will have a new game type called Spartan Ops which is similar.
No ODST comes as its own disc and if you own odst you get a beta of Halo Reach in 2010
No Halo 4 will not be coming out with a new story line but their is Halo ODST and Halo Reach and If you Buy Halo ODST you will be able to try halo Reach which comes out in 2010.
