Dear Frank --
I am not Miss Aida, but i can reply to you.
You are treating this as a rule-set, a series of actions that must be performed in a specified way at a specified time to get a specified result, like a video game or a sports contest or a laboratory procedure.
Magic is not like that. It is an ART. There is no "right" way to paint a picture, no "correct" way to knit a shawl, no "one" way to cook a casserole, no "proper" way to take a photograph. There are popular ways and efficient ways, and ways that are traditional in a large culture of people, and these judgements as to popularity and efficiency and traditionality do come from the lived and shared experiences of many people, and they are passed along in forums such as this and via face-to-face and telephone conversations -- but so much depends on who you learned from and who they learned from.
Music is also an art. There are so many styles of music in this world, and none of them is more "right" than others -- but here, in hoodoo, you are learning one form of -- well, let us call it music for a moment.
We have given you the chords, the structure, some common verses to the piece. Now you want us to tell you the strict tempo and the key. But we decline. The key is going to be YOUR choice, to suit your inclinations and also your limitations. The tempo too is yours to choose. This is your part of the artistry of the work.
But ... enough of metaphors. Here are some replies. They are not "answers" but "replies."
1) Morning is good for works of hope, optimism, cheer, and new beginnings. The day of the week would relate to your reason for the work -- Wednesday for business negotiations or court, for instance, or Friday for love. The days are based on planetary rulerships. This web page i wrote describes the relationships:

2) No.
3) No.
4) Orange is good for change, red is often used with Blockbuster as well, and white is the "universal" colour, good for everything.
This web page i wrote will give you the symbolism of colours:

It is up to you to learn to work with this symbol-set of colours, if you choose to do so. If you are colour-blind (and many people are), just use white candles and black candles, as you wish -- white for good and black for evil.
Good luck!
Which is probably why I may be wrong.
