Have careful with that little kick down switch. The plastic is old and brittle by now.
It looks like you have pictures showing where everything is going.
Remove the divorced choke from the manifold 1st so it doesn't hold the carb down.

First of all remove the transmission kick down switch on the drover's side, remove the throttle linkage nuts, remove the power brake booster vacuum lines at the back of the carb by holding the fitting that screws into the carb with one wrench and loosening the fitting that plugs into that fitting with another wrench.
Remove the fuel line, remove all the vacuum hoses, remove the two screws holding the choke stove to the intake manifold, and you should be clear to remove the two bolts and two nuts holding the carb to the intake.

Care ful removing the vacuum hoses, twist them a little before sliding off. Use the proper line wrenches  to remove the fuel line and the large carb fitting  can be difficult  to get a wrench on, there a special wrenches for that large fitting, a ground down 1"  open can be made up, some were 7/8..

I would put the air cleaner back on, then get a compressor and try to blow all the crap, dirt, sand and grit off the outside of the carb and manifold first.  You don't want that falling into the motor or the carb.

that carb looks to be in remarkable, low mileage shape.  It still is retaining all its beautiful factory gold color.

Read the factory shop manual. 

All the posters are right, be sure the kick down switch is carefully removed and make sure it is adjusted properly when re-installed.  Don't cut the metal fuel line into the carb. as so many do.  You will need a 1" tube wrench.

Don't drop anything into the intake manifold!
