comment How to upload a series of OS map sheets using QGIS and merge together?
I think the problem is that QGIS can't interpret the TABs properly. I'll add a possible way round this to my answer.

That said, I have come across problems with TAB files, historic OS TIFFs and QGIS before. If yours is the same problem there is a way around it, but let me know if you get sensible coordinates first.

Okay, make sure the TAB file is in the same directory as the TIFF and them load the TIFF into QGIS. Do the coordinates reported for the cursor as you move it round the screen make sense as OS coordinates? (eg. nnnnnn,nnnnnn.)

TABs are the MapInfo equivalent of TFWs and QGIS should be able to use them, I wonder why not in your case. If you load two of your (abutting) TIFFs into QGIS do they align properly?

Does the file load into QGIS when you go Layer -> Add Raster Layer?

What file extension does your LIDAR data have? For example it might be 'filename.asc' or 'filename.las'.

I still believe it can be done. Your bounty expires in very soon and when this happens I'll start another one running with 500 reps.

comment How to colour contour lines in .shp file when the lines are not meeting in QGIS?
Am I right in thinking you wish to have depths of (say) 0 to 10 metres in one colour, depths of (say) 11 to 20 metres in a different colour, and so on? Like this: dl.dropboxusercontent.com/u/45121071/classified.jpeg
