Hi Arnfinn - thanks for the Monroe link!
Question 1 - Frequencies used?No Solfeggio frequencies were looked into (unless the DNA stimulation of 3.5Hz is one?), but here's the listing:
_________________________________
Segment A
1) A constant pitch of 136.1Hz is used
This is the OM sound corresponding to the 32nd octave tone of the Earth year. Also the "frequency of the soul" - relaxing, soothing, balancing, harmony with the cosmos.
In conjunction, the binaural beating of this tone goes through the following:
16.4 - Spirit, liberation, transcendence
14.0 - Schumann resonance
12.0 - Centering, mental stability
10.5 - Frequency for healing of body, mind/body unity
9.00 - Correction of body imbalances
7.83 - Schumann resonance, grounding, rejuvenation
2) The tone which starts up at the 11minute mark is a higher octave of OM at half volume. Binaurals used:
33.0 - Christ consciousness and pyramid frequency. Coincides with voice 1 at 9Hz for some of the "weird effects" Michael Triggs talks about.
35.0 - Awakening of mid-chakras, balance of chakras
3) Another pitch at 70Hz - associated with mental & astral projection
Binaural beating of this is at 4.5Hz - Shamanic state of consciousness and Tibetan Buddhist chants
_________________________________
Segment B - 13 minutes
1) Constant pitch of 136.1Hz beating at 7.83Hz (Schumann resonance)
2) Continuation of 35Hz (chakra balancing)
3) Sequence of 7 notes for each chakra using Mesopotamian tuning
_________________________________
Segment C - 33 minutes
1) Om 136.1 Hz, binaurals from:
5.50 - Inner Guidance, intuition, heat generation (2.2 mins)
4.50 - Shamanic state of consciousness and Tibetan Buddhist chants (6.6 mins)
4.00 - ESP, astral projection, psychic abilities, "mystical truths" (11 mins)
3.50 - Feeling of unity with everything, whole being regeneration, DNA stimulation (7.7 mins)
2) Tones stepping from:
38.0 - Endorphin release
39.0 - Schumann resonance
40.0 - Astral projection in conjunction with 22Hz
3) 70Hz beating at 1.6Hz - Astral Projection
4) 63Hz beating at 0.7Hz - AP
5) 40Hz beating at 0.35Hz - AP
6) Beating at 22HZ - AP

Question 2I've tried out Deep Mind Ultra II, and in fact a lot of the astral projection frequencies used in Boxed Nirvana were based on this. The only thing is that Deep Mind steps down from waking to delta trance frequencies very quickly - I think Ultra II is only 20 minutes from memory? - and unless you're an experienced meditator your brain may not be able to "keep up", and you might not get the full effect.
Question 3 - Other Stimulation MethodsHaven't tried the ones you mention there sorry..
Question 4 - Chakra FrequenciesUse the tones as a supplement to visualization for stimulating the chakras.
Sources disagree on frequencies for each chakra, and the number and placement of the various chakras is even disputed. Some suggest that if there are any frequencies which affect the chakras, then they are probably different for every individual.
Hence to my mind,
visualising the stimulation of your chakras is the most important factor - imagine, and literally
feel energy flowing up from your base chakra and charging each one in turn.
So just use the 7 tones played as a cue to move your awareness to the next chakra, going through them in your preferred order and positioning. And yes, my preference is to follow Robert Bruce's convention: Base, Navel, Solar Plexus, Heart, Throat, Third Eye, Crown
Until I identify particular frequencies that have an effect (on me anyway!)
without additional visualisation, I've decided to go with the ancient "Nis Gabri" Mesopotamian tuning (for the musos, even more "natural" than Just Intonation), using a reference note of C at 256Hz. The binaural beatings match those listed at lunarsight in the 8-15Hz range (just in case it helps

)
Hope this helps!
