Hi Brian,
Well, to use teamspeak on IVAO you don't need any of that. The IVAP software will automatically connect you to the correct Teamspeak server and channels when you tune your radio to an active ATC frequency.
For example if you were flying Dublin to Heathrow (

) you would start the IVAO IVaP software after setting your plane up at the gate. You then need to file your flight plan through the ACARS page on the IVaP panel. Once you have completed this you press the connect button on the IVaP panel and you will be asked to choose a server and enter your network logon details etc. (I normally use the GB server but I find the DE2 server to be the most reliable) Once you are online you will see your standard FS2004 traffic disapear and if you have the IVAO MTL installed you will see other players on the network appear at the gates. (if there are any) After logging on you can check through the ACARS page on the IVaP panel to see if you have any local ATC. Say for instance you see EIDW_TWR on the list you would tune your COM 1 radio to the frequency it shows for that station. (118.600 normally I think) This would then automatically connect you via Teamspeak to the Dublin Tower channel..... It's that simple.....
Now if you want to use To talk to other EHM pilots who may be on line you can connect to the EHM teamspeak server you can read how to do this in this post:
