I don't want to throw a monkey wrench into your plans, but as a former Martin Logan owner, I want to make sure you take some things into consideration.
1. The sweet spot of ML is extremely small and if you stand up even in the "sweet spot" things quickly go awry. If you normally have more than one person watching/listening to your HT, then make sure you audition it outside the sweetspot and find it acceptable or the tradeoff versus cones worthwhile.
2. The models of ML you choose really should be dependent on the size of the listening room. They all basically use the same parts, but are designed to fill different size rooms. Your dealer should recommend the appropriate models for your room. Don't try to guess and make sure you have liberal placement options once in your room since they are a little finicky with setup.
3. If you like the cool look of the Logans and the wall of sound they present, I would also recommend looking at the Magnepan HT setup and pairing it with the Vandersteen sub. Using the 1.6 as fronts and wall mounted surrounds, you will likely save money even versus the discounted ML prices you received. Arguably, I think you would be doing slightly better soundwise, especially for two channel.
Don't get me wrong, I don't want to totally turn you off of Martin Logans. You can definitely get a very pleasing HT experience with a ML setup. However, I just found the risk profile for a ML setup to be a little higher and should be thoroughly considered to ensure maximum results.
