timing indicators

The 1st and 2nd photos don't show the timing marks good enough to confirm its correct. Refer to the photo below.

The red arrow with the word "Mark" above it should be aligned with the TDC pointer.

In the forth photo the camshaft sensor position "nub" appears to be in the correct position as shown below.

TDC Mark

I rotated my photo to look like yours.

Then I marked up yours.

There should be a short line approximately where the red arrow points to. The line is the actual timing mark for TDC, not the "0".

After cleaning, it was the best picture I got.
The marks are these?

I must align the point 1 to point 2?

correct

yes, that is the correct alignment for TDC.

Updating.
Guiderail broken.

I will only replace the cassete timing chain back on the right.
The recommended replacement parts for this are just that?
7U3Z 6K254 A ? Right Timing Chain Tensioner?
4L2Z 6M290 AA ? Cassette Timing Chain?

This parts list is correct?

All engine gaskets have been bought.
