There are a few more actually, including the ones I've quoted above. I normally do them via JSWED but rather than mention them here now I'll look at doing them 'manually' instead (like I did with The Beach object, three pokes to do it properly) for you over the weekend.
Watch Tower fix (although its sort of debatable if its a bug, I consider it to be) , Willy can jump from the conveyor as its too high up and end up in (undefined) The Off Licence. This was fixed in the BugFixed Edition actually. To fix manually its quite easy:
POKE 62167,171 (default value is 140) this changes the starting position of the conveyor from what would be in Basic "AT 4,12" to "AT 5,11" , its moved down one and left one
POKE 62169,9 (default value is 8) this simply extends the length of the conveyor another block as its been shifted to the left it looks odd otherwise.
POKE 62173,4 (default value is 5) this is the length of the ramp, reduced by one otherwise it extends above the conveyor.
A nice combi before / after pic illustrates this better really:
Made easy to match with the 'frozen in time' debug pokes hehe.
