comment Changing the color ramp in arcgis javascript
How are you displaying these GeoTIFFs? Are you connecting to an Image Service or are you somehow displaying them completely client-side using MapImageLayer?

comment Javascript Map (ArcGIS API for JS v 2.9) Not Releasing Listeners
The latest release of Dojo as of 5/1/2014 is 1.9.3. I think you mean ArcGIS JavaScript API v2.9 (which is now at 3.9), which is built on Dojo. What do you mean by "the listeners won't release the tools"?

comment Create Materialized View to Flatten ArcGIS JavaScript API Database
While you may be able to do this with a normal view or using joins/relates in your map document, for performance and ArcGIS compatibility reasons I would recommend what you already mentioned: Get the data provider to create a flattened table joined with all the data using SQL. Then add column & spatial indexes as necessary, register the table with ArcSDE and/or the geodatabase, and add to your map service as a normal layer. It's going to be much faster to draw than performing all of those JOINs on the fly.

comment ArcGIS JS API Legend Dijit not refreshing correctly
A couple thoughts: 1) In technique #2, have you tried calling legend.startup() again (instead of legend.refresh())? 2) Do you need to specify layerInfos to the legend constructor and refresh? If you just want to display all legends from all map layers, you can leave out the layerInfos argument altogether. 3) If you are concerned about destroying the "legendDiv", try creating another nested div (e.g., "legendDivInner") using dojo's dom-construct that can be safely destroyed when legend.destroy() is called. Then you can recreate the div as needed.

comment Toggling layers with arcgis javascript api 3.5
Just before calling .show() or .hide(), try inspecting the layer objects themselves by calling console.log(hospital2010kml); -- the object will show up in the developer console and you can inspect its properties/methods etc. If it's a valid KMLLayer object, it should have show/hide methods, as you said.
