Customize The Events Calendar plugg-in + add-ons -- 2

Hi! I use the The Events Calendar plugg-in by Modern tribe ([login to view URL]) with these add-ons: Facebook Events Community events I currently have some customization that limits me from updating the plugg-ins and adding the new 'Filter Bar' add-on as it only works with newer versions. My site ([login to view URL]) is an event guide where event organizers can create an account (buddypress)(paid service) and add their events to the site (through community events plugg-in). From there they also have the option to create eventbrite tickets (this is where customization comes in). What I need is to: update the plugg-ins and fix the design errors so I can add the 'Filter Bar' add-on. Customize the 'Facebook Events' importer add-on so it also imports the ticket_uri string to specified field. I can provide more info on request.
