When I first started to deploy Lync I tried creating VIPs for everything and eventually, I gave up because of the number of ports and VIPs needed. I was hesitant to use the iApp but it made publish Lync through the BIG-IP out to the web a breeze. The iApp built into the version I was using didn't support 2013 but here on Dev Central there is a newer iApp that supports both 2010 and 2013 and it worked great for us. It was a very well written iApp that made the process of integrating it in with our BIG-IP seamless. I highly recommend trying it.
As for issue 2, I remember when I deployed Lync 2013 there were some configuration items related to load balancing, can't remember now if I had to configure them or not but in the Topology application is where you will find them.
