Traditionally no, the mother of the bride does not give a speech at the wedding or at the wedding reception.
A good idea at a wedding reception is to place a gold sticker under a chair or a plate on the table and whoever gets that gold sticker at each table gets to take the guest's table centerpiece home. As far as the flowers on the Head Table, the bride can divide the flowers between her mother and mother-in-law or give them to sisters or best girlfriends.
Historically, the bride's family paid for everything but the flowers for both wedding and reception, alcohol for the reception, bridal shower, and honeymoon which the grooms parents are responsible for. In modern times however the bride and groom usually pay for their own wedding and happily accept contributions from family if offered.
The mother of the bride goes to the church rehearsal where the wedding party practices what they should do and say and then there is generally a Wedding Rehearsal Dinner after which all members of the wedding party (including the parents of the bride and groom.) There is no dress rehearsal for most brides or wedding party, but the bride and her brides maids would have to go into the wedding shop where the wedding dress and brides maids dresses were purchased to be sure no extra alterations have to be made on any of the dress and the mother may attend this if she asks the bride (which is generally not a problem.)
It's is a wonderful gesture on the brides part to give her mother in law a wedding gift. However it is required if she contributed in any way to the wedding such as money or time. Popular gifts include jewelry, engraved picture frames, photos, and items of personal enjoyment.
Usually the hostesse is the brides mother, but one has a choice if the mother is unavailable. There is usually a female friend who may have organised the wedding reception, or a close female relation. Formality may play some part in choosing a hostesse, so remember those who are not chosen can be tactfully thanked in speaches either for their attendance or some part they have played.
Make sure your mother's name is on the wedding invitation. In some faiths, candles are put in the church honoring the dead mother. At the reception, a moment of silence is done to honor her.

At a wedding reception, songs traditionally go in a specific order. They are first dance for bride and groom then mother and groom or father and bride.

Not at all. I had my mother-in-law deal with the rehearsal dinner (she really wanted to plan) and also took her advice for the wedding/reception. Some groom's mothers don't want to be involved until the wedding (they like to be surprised).
A Jehovah Witness Wedding is the same in most respects to say a catholic wedding. The only true difference is that the ceremony is not held in a church (never) and their is never a priest but a speaker, from the couples Kingdom Hall. So to answer your question the brides father typical gives away the bride unless the mother does it.
