1. You can apply now if you wish.
2. There's no need for a solicitor, the form is quite straight forward.
3. See here http://www.bia.homeoffice.gov.uk/euciti ... uropeanlaw for guidance on applying (you can download the EEA2 application form from the right of the bia page).

Hope this helps

 

This forum and others are full with similar questions. Try to read throught them. It's worth it!

The validness of your EEA family permit doesn't matter --- in principle. Your right to be in the UK derives solely from your relationship with your EEA partner. However, in practice you will need some documentation in your passport stating that fact, e.g. if you want to travel, find work, open bank accounts, etc. (read the related threads).

Processing times for the residence card at the moment seem to be around 6 months although some people are waiting longer, and sometimes much longer.

Hiring a solicitor is probably a waste of money. You'll find references to the documents you need on the EEA2 application form. Some people recommend not include the passport right away but wait until Home Office explicitly asks for it. Just write a cover letter stating this fact and include a copy of the relevant pages only.
