First of all my question is , how to save the styles and his options , because after upload files of newer version my style was being return to default view (no logo, customized CSS options).
Styles and modifications from 3.0x are not carried over to or compatible with 3.1x

It does the update in numerous smaller steps. Just keep pressing continue. It'll get there in the end. In 3.0 it used to try and do the lot in one go and often timed out so now it's broken down in to user prompted stages.
I wasn't entirely sure 3.1 could run from as far back as 3.0.1 but I might be wrong.
You might want to look in to updating to 3.0.2 and then 3.0.6 and then 3.0.13-PL1 (as these were big steps in the 3.0x line) and then to 3.1x. It would only require file uploads and the database_update being run each time.
