Hi Susan,
I was very interested to see your post because I just finished up week 6 of P90X, and love to read what others think. I, like you, am tall, and have a hard time with pushups.
Pull-up bar: I bought a Power Tower. Yes, it takes up a LOT of room. I still cannot do one unassisted pullup or chinup. I usually do the first set of each exercise assisted on the way up, and then do the negative unassisted. I then do the second set of each exercise with bands wrapped around the bar. I think the bands with a door attachment are the best option for you, because of your space limitation.
Horse stance: I point my feet in the same direction as my knees. It feels better....
Pushups: I have the same question as you; is it better to do the pushups with the limited ROM, or to modify to negatives or knee pushups? I do as many as I can on my toes, but my ROM is very shallow until I get warmed up. It seems like I can do more as I go through the workout. I do ALL diamond pushups and dive-bombers on my knees, BTW.
In general, I skip the strength workout warmups. I do a short cardio warmup before skipping directly to the P90X strength work. I love Chest/Back, Shoulders/Arms, PlyoX and Core Synergistics. Back/Biceps seems like biceps overkill to me, considering my biceps wear out and cause my pullups to be even MORE impossible! Chest/Shoulders/Triceps is OK. It goes very fast, and I am never sure if I got a good workout or not! YogaX is tolerable. I'm not a big yoga fan, but I see the benefits. I have substituted some other power yoga in its place when I don't have 93 minutes. CardioX is short and fun. KenpoX is just OK, and I've substituted Cathe's kickboxing most of the time. I have only done XStretch once, and it is long for me. I'd rather do 30 minutes, so I sub Karen Voight's Yoga Stretch. Ab Ripper X is TOUGH. I substituted Tamilee's IWT Abs#2 today, and it was actually EASY after doing ARX so often, so I know ARX is strengthening my core. My core is relatively weak, so I need a lot of work there. Have I missed anything????
Good luck with your rotation.
BTW, I've written down your 9 day week rotation to try when I'm done with the P90X. It sounds like just what I need to do.

P.S. I'm REALLY looking forward to the Hardcore Series, and think that the negativity found at the beginning of this thread is unnecessary. I"m sure Cathe doesn't mind....
