Which is why they went and got it from the Reaper. And no, if the thing can put up Mass Effect fields to trap us, the Collectors would still see the signal.
Which begs the question, why did Shep and co even bother getting it if the Collectors would know it isn't one of theirs? Why didn't TIM think that one through?
Contrived Macguffin methinks.
To address your second line, I think you're misunderstanding how the IFF works. The Omega IV relay doesn't get to selectively choose who survives/does not survive the journey. The IFF is a targeting system, which allows precision-based relay jumps and prevents drift in space. They obtained the IFF because it would allow them to hit the "safe zone" through the relay.
What is a plot hole is that the Collectors were not already aware of the IFF sitting inside the dead Reaper.
Brown dwarf.
Explain, please? 
Brown dwarfs are
sub-stellar objects which are too low in mass to sustain
hydrogen-1 fusion reactions in their cores, which is characteristic of stars on the
main sequence. Brown dwarfs have fully
convective surfaces and interiors, with no chemical differentiation by depth. Brown dwarfs occupy the mass range between that of large
gas giant planets and the lowest-mass stars; this upper limit is between 75
[1] and 80
Jupiter masses (
MJ). Currently there is some debate as to what criterion to use to define the separation between a brown dwarf and a giant planet at very low brown dwarf masses (~13
MJ ), and whether brown dwarfs are required to have experienced fusion at some point in their history. In any event, brown dwarfs heavier than 13
MJ do
fuse deuterium and those above ~65
MJ also
fuse lithium.
Cleaerly with the radiation, heat, and interferance....The reapers were not able to find the dead body. Also, the fact that they knew that if anyone found it, they would never know what the bady was unless they met a reaper before. Since they normally surpise beings with this info first then inslave them, mostly likely they thought that anyone that found the ship and new what it was would be indocrinated.
