1. I am anticipating no more than 10 records (usually just one or two at a time) sent up as an array. The SQLite database is queried, an array created and sent to a remote CFC via RemoteObject.
2. No more than 10 records received from a CFC as a Query object, which will then be put in an ArrayCollection, which will be looped to do Insert or Replace into a SQLite database. If a user is scrolling a list while this is happening, will it be obvious? It seems like the list, with an IconItemRenderer, is pretty resource hungry as is. The list scrolls nicely and is the most intensive view...the rest are somewhat static once rendered. However, my testing phone is a Motorola MotoX, which is pretty new and beefy, so it will most likely be worse for many users. Any thoughts? Is there a performance benefit to using RemoteObject in ActionScript rather than MXML? Or is the compiled version pretty much the same?

If the response is large or has complex data types, the native parsers/deserializers can be very slow. While the response is being processed you might have a freeze, sometimes a very significant one. There are a lot of things you can do to work around it... get data in smaller chunks, write your own custom responders, or we have had some success using workers to process the results before returning the processed response to the main SWF. What you choose to do depends on your backend infrastructure and what communications/API frameworks you are using. In my experience, with less complex/smaller data sets I've had good luck avoiding workers and simply suppressing attempts to convert objects back to strong types and instead writing my own deserializers.
