Hi,

You have a lot of these. Here are some very brief comments.

prim and proper fastidious, ceareful, neat      

to and fro from one place to another, and back again, repetitively

odds and ends miscellaneous, unimportant, unrelated things

hard and fast clearly defined, not easily changed, eg rules

tooth and nail with every effort, fiercely

down and out no money

length and breadth everywhere

safe and sound  very safe and well

ins and outs    petty and complete details and methods 

cloak and dagger      very secret

spick and span      very clean and tidy

up and about      normal, healthy, not sick anymore, rejoining the world

ups and downs      good times and bad times

song and dance     unnecessary fuss and difficulty

collar and tie     wearing a neat shirt and tie 

pins and needles   small pains and cramps you get, for example if you sit on your foot in an awkward position. Also use to refer to a feeling of suspense and anticipation.  

sick and tired      losing patience, angry

bits and bobs similar to 'odds and ends' above

Best wishes, Clive
