Safety precaution when removing trailing arms?

[72tutone]

Any words of advise? I need to remove my trailing arms. Any particular order in doing so?
Steps I have gathered so far from searching on the board are as follows.
1.Block front wheels
2. Jack up rear frame place jack stands
3. Use jack to lift the rearend up.
4. Unbolt the front first. Let lay.
5. Unbolt the ubolts.
6. Unbolt the spring cups last?
Does this seem like a good order? Are the springs under a load?
