1: I so dont get the flowing energy ok, because I am a lone trainer I would have to practise what Bruce Lee did when he looked like he was doing isometrics (page 82 in basic training (blue book) ) but how does it work and really what is it all about?
Flowing energy (or chi as most call it) is developed through live interaction with an opponent by doing energy/sensitivity drills. Unfortunately, that is about the only way to "get it" as the saying goes!
2: Is it better to kick different surfaces to get a feel for different kind of landings all I have is a punching bag .. (pretty light (just filled with rags). I have 2 paddles but no one to hold them for me any suggetions?
Variety is the key to thorough development of your techniques. As for your bag being filled with rags, 90% of the heavy bags on the market are filled with leftover material scraps from martial arts uniform manufacturing! LOL Therefore, you are right in there with the pros on that! Remember, too much training on the heavy bag will retard your speed! Believe it or not, I have gotten some really great workouts kicking at leaves on tree limbs! This is great for developing accuracy and speed! There is nothing to slow you down, because you know that you aren't going to break your foot kicking a leaf!

Pick a leaf and go for it!
3: I am going to need some strengthening exercises for my hands as when I punch for ages between my little finger and the one next to it cuts?
I am not really sure why this happens with some people! One of my senior students, and Apprentice Instructor Level V in my organization, still has problems with that area of his hand when he does lots of punches on focus gloves. I guess it is just a matter of proper progressive conditioning of the hands! I would suggest using a wing chun wall bag filled with progressively harder substances over a period of time. Immortal makes an excellent wall bag!
4: In all examples in books Bruce Lee waits for the opponent to attack first is this the way to go? If not how can you attack at an oppening if there will always be an opportunity created for your opponent once you engage?
Well, interception is about stopping the opponent right as he starts to attack, but it takes lots of training to get to this point! Now, if you just go out there and start jumping on people just because you think they might want to fight, then you are probably going to be in some serious trouble! What you have to find is that happy medium where you learn to anticipate trouble and leave before it escalates, ot learn to take the opponent out at the earlist sign of aggression! I prefer the latter!
Keep Blasting!
