Help

My droid is acting extremely weird lately. Seems to freeze, i dont get my Bloo facebook notifications unless i open the app itself, i only get my hotmail new emails in my status bar randomly once a month, i bought GDE and it will not run without force closing constantly, i installed Google Voice but do not have an invite and when i switch my service back to the my provider for voicemail it still runs the Google voice and i can't check those voicemails, i also have problems with some facebook contacts and if they're number on facebook is without the area code i can't call them so i try to edit their info and it still does not work. I am wondering if i need to just do a hard reset and what the advantages and disadvantages of that is or what i could possibly do to make my droid run better

TIA
