While this particular forum is specifically for the Master Cleanse, so many people ask about the Ultimate Clease that they really should start a forum for it. But since they haven't, I think your questions should still be answered.
Yes, you can combine the B&Ps with Master-Cleanse and many people also successfully add a parasite cleanse with it as well. Some people cannot tolerate the toxins created with a parasite clease when combined with the Master-Cleanse so it really will be a personal decision. From what I've read many people end their Master-Cleanse or Ultimate or 3-way Cleanse with a Liver cleanse either immediately following or with in a few days/weeks.
It is very important to note that you MUST increase your water intake significantly if you plan to add the B&P to your routine..."half your body weight in ounces" or more. Your lemonades, tea, the amount of water used in the SWF (Salt-Water-Flush) and the amount used with the B&P all DO NOT count toward this water amount. Those liquids are all in addition to the extra water you need to drink. Believe me, it makes a HUGE difference in the results you will see.
For what it's worth, I'll tell you what my shedule has been - I'm on day 7. First, I started with the tea two nigths before I officially started the MC. On day 2 I had my first SWF. On day day 4 I started with 1 B&P and am now up to 4 each day. On day 6 I stared with a parasite cleanse - Paragone - and so far so good with that.
As for a daily schedule my day completely revolves around when I have to drink a particular thing. Pretty exhausting but I really look at it as a way to develop better discipline for when I'm off the cleanse(s). So many things have to be taken "on an empty stomach" that I actually worked this schedule out and refer to it constantly. Here is my crazy schedule:
