You can just use your account - as long as people are okay with the potential spam of the logs. If other users might be annoyed at it, making a bot account is really simple, it's just creating an account, checking with the community that they're okay with the bot and contacting Staff to add a bot flag.

As for the tasks: yes, you can use AWB for fixing the galleries. You can do a simple Find and Replace for that.

For deleting all articles in a particular category, I would suggest using AjaxBatchDelete, which is a user script that does exactly what you'd want.
