Compositing 3D into a still image - help plz

It may have been a good thing I was away for the last challenge as I have no idea how to do this.

As some know I went to Escape studios today in London to enroll on a VFX class starting in May. One thing the tutor told me to work on is getting 3d in to real images. Now I know what I want to do - put some thing in to my street as during the day its empty and I think there are some cool area to take photos of for a back plate.

I think it goes

1) Take photo`s for back plate and ref
2) Model the object
3) create some proxy models for stuff in photo (eg floor)
4) Line up object in photo (not sure how)
5) Match the lighting (not sure how)

6) Use render layers to create realism
7) Comp together

Its the bits in red I have no idea how to do -

For part 4 I know how to do this for video (matchmoving) but how for a still - is it just eyeballing it.
For part 5 - I know how to make panoramic photos (full 360) but not hdr photos. Our they really needed
I do have a large collection of hdri images - they are just not off my street.

Basically I need help on what sort of photos do I need to take for reflections and lighting - and how (if a hdri) - after the last challenge I know some of you know how to do this...
