if this is the rough cast 1930's finish it is straight forward but hard work. you posed a number of questions and the answers will very much depend on the condition of the render and the paint work.
1. to clean it off you can use a pressure washer, be prepared for flaky paint to go every where,
2. if it is flacky paint use a sandtex stabiliser this is a very runny product so a 4-6 inch emulsion brush and an old paint pot are the best tools
3. use sandtex paint it is good for 10 -15 years if done well and not near the sea, if you are in a coastal position every 3-4 years
ladder and a good pair for boots
tower is great but not as quick
best method of application to rough cast is a top quality wall brush for smooth render a roller is best and a long extension pole. I have struggled for years with a broom handle but buying the real thing was a bargain it save hours.
pay someone if you want! it do the job your self budget 10-15 liters paint and 5 liters stabilizer the so materials 50-100 quid and a long weekend of work for you.
