Welcome to the Q&A Forum

We have a variety of issues at the moment, and need some advice. First off, we have a HUGE indexing issue across our entire website. Website in question: http://www.localsearch.com.au/ Firstly
In Google.com.au, if you search for 'plumbers gosford' (https://www.google.com.au/#q=plumbers+gosford), the wrong page appears - in this instance, the page ranking should be http://www.localsearch.com.au/Gosford,NSW/Plumbers I can see this across the board, across multiple locations. Secondly
Recently I've seen Google reporting in 'Crawl Errors' in webmaster tools URLs such as: 
http://www.localsearch.com.au/Saunders-Beach,QLD/Electronic-Equipment-Sales-Repairs&Sa=U&Ei=xs-XVJzAA9T_YQSMgIHQCw&Ved=0CIMBEBYwEg&Usg=AFQjCNHXPrZZg0JU3O4yTGjWbijon1Q8OA This is an invalid URL, and more specifically, those query strings seem to be referrer queries from Google themselves: &Sa=U&Ei=xs-XVJzAA9T_YQSMgIHQCw&Ved=0CIMBEBYwEg&Usg=AFQjCNHXPrZZg0JU3O4yTGjWbijon1Q8OA Here's the above example indexed in Google: https://www.google.com.au/#q="AFQjCNHXPrZZg0JU3O4yTGjWbijon1Q8OA" Does anyone have any advice on those 2 errors?

We're rebuilding our entire website in angularJS. We've got it rendering fine in WMT, but does that mean that it's content is detectable? I've looked into prerender.io and that seems like a great solution to the problem of not seeing any static HTML, but is it really necessary? I'm looking into this as I'm having the argument currently with my devs, and they're all certain that Google renders angularJS fine.
