You are not going to be able to easily upgrade your site to 1.5. The biggest problem you face is that Mojoblog is not a 1.5 extension and is no longer supported. At a minimum, you will have to find a replacement for that. How you use it will determine which extensions are suitable replacements, but there is almost certainly an extension that will fit your needs. Blog type extensions are plentiful for Joomla 1.5.

In order to migrate from 1.0 to 1.5 you can follow the official Joomla guide - http://docs.joomla.org/Migrating_from_1.0.x_to_1.5_Stable
