I currently have a road bike with the following setup for the gears:

9-speed Tiagra front and rear derailleurs, Sora shifters, all from 2009: 30/39/52 Crankset 11-25 Cassette.

I need some more low gears for hilly areas, and I am thinking of switching to a 9-speed Deore XT derailleur and 11-32 cassette. Is it possible / compatible? Do you think that cross-chaining would be an issue? Will I need a new chain?

Yes, always put on a new chain when you change the cassette. – DanS Sep 28 '12 at 8:31
I just installed the setup that I mentioned in my question: Deore XT long cage, 11-32 cassette and new chain. It works well. There is slight cross-chaining in the large-cog/large-chainring and small cog/small chainring, but I was expecting it. I'll never use that combination anyway. – Javier Sep 30 '12 at 1:09

Yes, that will work just fine. I have a similar setup on my touring bike, Tiagra shifters and an LX derailleur.

Yep, so long as it's all 9-speed it should be fine. 10 speed mountain stuff uses different pull ratios and may have issues with road shifters. – Benzo Sep 26 '12 at 0:24
