Please Help A Noob Out

Hello. I just got my Mogul (Alltel) and like it but I do have some complaints. First, I can't keep a signal in my house. It goes from 2 bars, to 1 down to none and I keep loosing calls. Is there anything I can do to improve my signal or am I stuck with the crappy signal that I have. Also, about half of my text messages don't go through. I get a error message back saying would you like to try and resend the message. This is what the message said:
"Text Message Retry
330-814-8772
Error Class: Temporar
Cause Code: Othr.Gnr:P
Message failed would you like to retry?"
This is getting so frustrating. Also with the text messaging it is soo laggy. I disabled the text predict thing and that doesn't work. I don't know if it's because I don't have a memory card and I'm using a lot of the phones memory or what. Lastly, it takes a long stinking time to charge the phone. I don't understand why my phone looses power when it's charging. It happend to me twice tonight.

Someone please help me, Jon
