i know my edirol fa-101 has a mintor control. in that you can directly monitor inputs through the interface, and mix them into output 1/2. if you have a "SOFT Ctrl" or "Mix" knob on your edirol, play with these. it may be you are hearing the input signal mixing with the output of Reaper (15ms later, or whatever your latency is).

i *think* the latency numbers are input/output so its 8ms in/9ms out. this seems likely, tho correct me if im wrong. in which case you have 17ms round trip without cpu processing (ie effects etc, which normally only add a few samples)

thats pretty low, tho you should be able to get it lower.
just keep pushing the buffer lower, until you start getting artifacts (clicks & pops).
as you add more tracks etc, you will have to increase the buffer as the cpu has to process them as well as 'pass' the audio.

also, for lower latency, the higher sample rates are better. if the buffer is 1024 samples, then 44.1khz will have a longer buffer time in ms than 48/88.2/96 khz will have as its sending less samples per second.
but thats only if your computer doesnt fall over
