Once I put my passphrase in and I select the proper coin which "Derivation Path" do I choose,
Did you put your actual BIP39 mnemonic backup phrase from your coinomi wallet into the Ian Coleman BIP39 website? 
If so, you need to move all your coins ASAP, as you should consider that mnemonic compromised!Or did you put your BIP39 mnemonic into an "offline version" of Ian Coleman (downloaded and run on a computer not connected to any network)? That is still "bad", but not as bad as typing your mnemonic into a website.
