The 3 mounting nuts should be replaced, but the new top mount may come with them anyway. The new damper should come with a new shaft top nut.
The only adjustment of the front suspension on a 260 is toe in/out. You are not touching any parts of the suspension which would be likely to affect that though. The camber/castor angles are not adjustable. There may be very, very slight camber change as a result of any play in the 2 lower damper mounting holes, but it would be insignificant and difficult to adjust without (say) buying eccentric bolts.

Torques:
Top Mounting 3 Nylocs : 22 Nm
Big nut on damper : 58 Nm (I use a 18mm crow's-foot for that one while someone else holds the shaft with a hex/Allen socket).
Lower 2 strut-bolts to knuckle : 155 Nm.

If you wish to check alignment:
Front wheel alignment - toe in - 6 minutes per side (12 total)
Front wheel camber - negative 1 degree 10 minutes
Check with Tyre pressures: Front 34 psi and Rear 36 psi for 18" wheels, or Front 34 psi and Rear 40 psi for 17" wheels, and with a full tank of fuel.
