Check here. Read about half way down the first post to find the CE version of the SP2 fix. Try that out and see if it fixes your issues. There is no auto-install patch, because CE has been unsupported by Gearbox thus far. The possibility for future patches remains, but it is virtually impossible to attract 1000 players to CE at this point in time.
To answer your second question: yes, several maps feature the plasma sword. Maybe someone else can chime in as to which maps contain this weapon, as I don't keep track, since it's a fairly useless weapon. In a few days, Zanzibar and New Mombasa with the Halo 2 mod will be released and will also feature the plasma sword, gravity rifle, and a host of other super spiffy mods. Keep your eyes peeled. ;)
