Sounds like an okay car. 103K miles is decent. Congrats!
The clutch is probably original and with luck, oughta last another 50K miles or so.
At over 100K, the belts should have been done many times. The maintenance interval is 45K miles and/or 5 years (or less)
Camshaft / Balance Shaft Belt Information. Many people will change them at 30K miles and/or 3 years.
With a car where the maintenance history is unkown, the most prudent way is to replace the belts and rollers as well as the waterpump (which is probably oririginal and due).
However, if there's no end play in the waterpump pulley and it turns freely and there's no sign of weeping, you might skip that. All while knowing of course, that you'll have to pull the whole thing apart again if it goes bad.
The rollers can be re-used if they spin freely without noise, and have no end play. A new roller spins easily but with some light resistence; as they age, they spin more and more easily until they start making noise and start to wobble (have end play).
But like I said, the most prudent course is to replace everything.
The kits I've seen tend to include things I never end up using.
