Hi TCK,
Here is a link to a really good article my great grand teacher (3 generations ago), Li Ya Xuan. Reading this will give you alot of information and alot to think about.
http://qi-journal.com/Taiji.asp?-token.SearchID=Li%20Ya%20XuanI would really like to see a video of your progress now if that was a long time ago. As I said I think you have a lot of potential.
For your questions:
1. Keep doing standing meditaion, practice lots of Forms and be mindful of that problem when you practice Push Hands. Thats why I suggest you try using "give up" for a while and dont be concerned about getting moved a little. eventually you will be able to keep root in a relaxed way.
2. The concrete will probably never attack you. Taiji is not really for use with inanimate objects because it relys on both your nervous system and your understanding of your partner's. It is dynamic and alive.
Through practicing Push Hands you will learn "what is hard", "what is soft" and find the balance in your power. Forms and Standing are improtant for this also because you will get more relaxed and let your power come out correctly.
3. Movement in all directions is literally initiated from the waist, rooted to the heel and guided by the mind and spirit. Try to start each motion from the waist. Rotation on the vertical axis guides movements laterally. Slightly tilting like a scale and using the hips and spine guides the limb movements vertically. So combining these directions of the waist gives the arms and legs momentum to carry out each motion - in both Forms and Push Hands. Even when you step - send out your hips first.
4. We don't have Sky Form in my lineage.
Taiji really requires time with a good teacher and it takes time to find one. Keep practicing what you know and read the TaiChi Classics over and over. I have compiled some links to Classics on the internet here:
