You really should reboot between flashes. Either reboot into the ROM or select 'Advanced' from CWM main menu and then select 'Reboot Recovery'.
I'm downloading the latest build now. Will check it to see if the launcher was included this time cause it wasn't included in the last build. It wouldn't hurt anything to install the Catapult patch even if it's included with the ROM tho.
I always do a factory reset. This wipes user data, cache, .android_secure, and sd-ext if you have one. Then I goto the 'Advanced' option in CWM main screen and choose 'Wipe Dalvic cache' and also 'Wipe battery stats'. Hopefully this may help.
