Lately when I try to start up the TR3 the starter is very sluggish. Very slow cranking until it finally fires. The battery has a full charge and posts are clean and tight. I'm going to check the connections at the solenoid and at the starter itself to see if they have come loose. Other the the starter itself feeling it's age what else should I check?

What's the battery cranking power? A volt meter may show 12 volts, but that's without any load on the battery.
If the battery has a few years on it, the voltage may be 12 volts, but the "cranking power" itself may be weak. A better test is the voltage *under load*. Example of a battery load tester:
(also check ground straps, and starter lube if needed, and starter speed when all plugs are removed)

Check and clean all the grounds (body, frame, block and battery). Jump across the solenoid terminals with a screwdriver. If that doesn't diagnose it, first using the vehicle battery, use a pair of jumper cables to connect the starter body (one of the big bolts holding the starter on will do) to the ground post and the other from the power post to the power input stud on the starter. If that doesn't pep the starter up, try the same with a known good battery not installed in the car. These steps will give you the answer.
