Trap Toolkit

[Varyon]

I don't have DF 4, but I can't think of any realistic kit that would somehow make any but a very narrow subset of traps easier to find.

As for bypassing traps, there are basically three main methods. One is simply springing the trap in a way that won't harm you - this would require you to figure out what the trap does and how it's activated (likely using Traps skill or similar), then using a decoy, barrier, or whatever. The second is to disable it by jamming the gears, cutting the tripwire, etc (Traps to figure out how it works, then something relevant to break it - which may just be Traps again). The third is to figure out how the owner bypasses it and using that - this might be a specific path you need to take, a hidden switch for disabling it, and so forth. For DF purposes, I would typically assume this bypass is in the form of a key that turns the trap on and off (or accesses some sort of "control panel" to do the same), allowing Lockpicking (or at least a lockpicking set in conjunction with Traps) to be used to disable it.
