OK so I see how to address particular LED's using the fill command. Is there a way to make the startLED a parameter so it can be incremented in a do loop?

not at this moment unfortunately
if you don't have too much LEDs you can just copy/paste I think

you can do this now with {0} which will be replaced by loop index and extra parameter can be added to the loop = step.
do
fill 1,FF0000,{0},1
loop 10,2
this is the same as:
for (i=0;i<10;i+=2){
fill 1,FF0000,i,1
}
if you have a nested loops you can increase the {0} to {1}:
do
do
fill 1,FF0000,{1},1
loop 10,2
loop
To create complicated animations it's better to run the ws2812svr as a system service listening on a TCP port and send commands to it with external program like python,C# or shell script.
Create png files with each pixel the color for the led you want and load them with the readpng command in a loop is another possibility. The newest version can read entire png/jpg files with a delay between rendering each pixel line.
