When creating a new message, if you just type the name without selecting anything and then just tap the box where you type the message, it will add the contact for you and it should pick their mobile number. After it adds them, you can tap their name and press edit, and it will show you which number it will send it to. Sorry if that doesn't make sense...

As for the keyboard lag, try disabling the visual feedback. There's a reg edit I posted for it a while back but I don't know it off the top of my head, and I can't search for it because I'm on my phone. Im not sure if it will work, as I haven't tried it.
