Theoretically any city can access all three Market Wards, but yet all three Market Wards are still separate. All three cities have access to the three 'Mercantile Houses' from where you can search the Market Wards of the city related to that Mercantile House. So from Gridania, for example, you could check the Market Wards of all three cities. HOWEVER, each Mercantile House can only search within the city it corresponds to, so if you do a market search in Gridania's Mercantile House you will get a result from the retainers in Grid, if you do so in Ul'Dah's Mercantile House you get the results of Ul'Dah.
I've been having a fair bit of luck selling in Gridania myself, my Limsa Retainer has had pretty minimal luck. I'm on a different server, though.

Just don't dispatch them to Ul'Dah. What happens is that if it has a deployment failure (that is, the ward chosen is full) it does not gives you a 'failed to deploy' report. However, if you ring the bell again the menu will tell you that your retainer is in a weird place (generally The Dunes for Ul'Dah) if it failed to deploy properly
