I think it all depends what position you want to cover in the team. A junior position should not be impossible to reach. You can get good in languages like Python in a matter of weeks. It may take more for web development although.
Databases: as all web sites are dinamic, it is important to understand a bit about databases.
Memory: people with more experience than me can have a say here. But I really think you should think about this later and only in case you want to play with lots data.
