Our responsa on the matters of the Amidah and the Birkat HaMinim is written by consensus.
In general it is as written to you before:
There is no Torah command to pray thrice daily.
* However; There is the example of both Daniel and David
* When one prays we should follow the pattern given by our Messiah
* One should recite the Shma daily as is customary
* One should remember the admonition of Shaul HaScliach to pray without ceasing, this is best done by learning the pattern of the traditional blessings and using them, or your own, were appropriate
* Phrasing such as:
"Praised be YHWH for such a beautiful day"
"Praised Be YHWH for giving me a loving mother" When you see her
"Blessed am I of YHWH for such an adorable wife" When she looks especially pleasing or wears a beautiful dress etc
* Be mindful to never include any thing not in line with Torah such as pagan things of our fore father or the commands of rabbis that are not in Torah (the candle blessings etc)
If you wish to know acceptable replacement bracha for those that have 'as commanded' write me and I will send the ones we have, some are enclosed
The community prays three times each day. As a community together we should prayer in harmony. Such is the purpose of liturgy. The Amidah is liturgy and should be prayed with community, if however one can not join their community they nay say the liturgy if they wish.
As for the Birkat HaMinim:
One should never pronounce a curse on anyone, especially oneself. This is a clear violation of Torah and the words of Messiah as given in the parable of the Samaritan.
