I'm considering connecting an HP Procurve 2810-24G to a Nortel 8600. The Nortel 8600 side is currently configured with an XD Gbic and connected to a BS 450(probably about 2-3 miles across town). I'd like to replace the BS 450 with the HP switch, but not sure which mini-gbic to install in the HP. I'm thinking the J4860C LH but not sure as I can't find an XD designation for the HP product. Appreciate any help.

You might be in a tough spot - those XD optics are rated at 50 km (in the 10G world they'd be called ER optics). The problem is that I haven't seen other vendors with XD/ER optics in the 1G product space. As you know the J4860C is an ZX unit that would be rated for 70km, and I'm not sure they can be interchanged.
I'd be worried that an ZX unit would be too 'hot' for only a couple miles of fiber - it is possible to burn these out so even if it comes up I'd watch your dB levels and have a handful of fiber pads ready.
Do you know what kind of dB loss you've got end-to-end? You're within the distance that LX (10km) optics could work, that hardware would be a lot cheaper - perhaps enough so that you could replace both sides for less money than buying ZX optics for the edge side. I think J4859C is HP's LX (10km) unit - the Nortel side would be something like AA1419002.

I use LX optics in a Metro dark-fiber Ethernet ring of two 8600 and 5 5520 nodes using LX optics for over 5 years and I have had no issues with them, and I know some of my links are over 10k and some are pushed longer.
Actually, I've never tested my dB budget but the City pretty much rejects any splice of theirs with any loss, and I try to keep the number of junction points to a minimum.

As an option you might want to look at using BX optics and double your bandwidth. I'm getting ready to do that with my dark fiber between my two 8600s that are 8 blocks apart, and have my highest traffic. The BX are able to shoot both ways on a single fiber then use MLT and VLACP to cover redundancy of fiber or SPF failure, plus provide 2 Gb of bandwidth.
Haven't implemented it yet but have the parts. Instead of the Procurve you might look at the 5500 or 5600 switch platforms instead, as I believe they accept the BX optics also.
