1- a good router table insert, Kregg or JessEm or alike.Baptist
is the biggest online store for woodworkers in Holland and sells components to make your own router table. There is not such a big market for this here in Europe, so there's not much offered. They import most of their components from America.
Google also found this
company in Belgium. Not sure how much trust I would put in a company that uses a hotmail account though.
2- t-track that fits Festool clamps.
No idea. Most T-tracks I found are smaller.
3- finally the 8020 profiles, or another brand.
Bosch Rexroth is the leading manufacturer of that type of aluminium construction profiles here on mainland Europe. Same Bosch as the powertools, just another division.
There's a company just a few kilometers away from me, named RS Components
that sells them. Unfortunately I can't buy there as a private person.
