In fact, the Carmichael Sprint workout DVD, the first thing they mention is to increase your tire pressure 10-15 pounds over your normal.
You can do stomp type intervals on a trainer. Quick accelerations, whatever.
If you use a trainer tire, remember it's there. This sounds stupid, but the old ones were a godawful orange for a reason. Now that they are black....and they are an extremely hard compound so riding on them is not a good idea.
I tell people to just hang on to their old tires when they switch them out and use them for the trainer.
