Do you have a sister, Mum, cousin who would be your birthing partner ?
Don't feel bad about him not being with you and if he changes his mind and wants to be present at the birth - remember this is totally a choice that you and only you make. If you don't want him there, then he doesn't get inside the labour ward. he has no right to be there, especially f he has been abusive.
As he's your husband, he will automatically be on the birth certificate and I think he can register the birth, although I'm not sure about this and it will depend upon where you are based. Your spelling of labour suggests you may be state-side so the legal side may be different to the countries within the UK.
There is no need to tell him you're in labour and likewise I wouldn't be rushing to inform him of the birth either.
If you have a different surname to him, you are not obliged to use his, even though you are married. You can use yours or any other surname for that matter.
As for names - my personal preference is for strong, traditional names, eg Daniel, Matthew, Thomas for example. I wouldn't be too worried about having a name before the baby is born. I was all set to call DD one name, but she just didn't look like the name so we called her something else.
After the baby is born, can you spend sometime with your parents for support, or could they come to you ? talk to your midwife now so she can offer support.
