Sounds like you want to compete and fight for most of the right reasons.

I read you talking about a long lunging circle step earlier. You'll get into that pretty soon I believe. We call it "humbo" step (hubbie likes the Kempo term I guess because they have a similar stance in Kempo) or C-stepping. Boztepe uses that alot and can really shoot forward and close the distance on a fighter. Scary. lol!
But, that will take alot of time before you can do that.
When you start stepping in to "pressure" the opponent, take your time. I usually just take smaller steps in basic stance (Sil Lim Tao stance, whatever ya'll were calling it eariler) until they run out of room and have to make a move. This leaves you uncommitted and gives nothing to your opponent to work off of, no energy, no inertia, no telegraphing. As soon as they move, whether a feignt, punch, kick, or shoot then you "shoot" in with your C-step, or advanced stance. I'm lazy, so I usually tend to step forward with a heel kick as I step into their stance. This will cover you if they happen to kick, and works almost every time.
Don't worry so much about covering alot of distance to chase your opponent. This mentality could set you up to play their game and bait you into whatever combo, takedown, etc. they are planning.
Just, walk. Relax. And wait to respond to their movement. Let them jump around all over the place, that will just save up your cardio and waste theirs.
Anyways, I think it's cool that your wanting to cage fight. We need more like you. Don't let people convince you too much on all this cross training and grappling/wrestling stuff yet. Just stick with Sifu and train the dickens out of what your learning now. Your doing great so far. Very dedicated and very energetic by what you say about your training. You train way harder than I do! lol!
I don't know if you chainpunching the bag for 10min. without stop or what, but if your doing that already then,.. Damn! lol! Very good! Just quite using those shoulder muscles. If you want big shoulder muscles work weights or restiance bands. Use your lats when chain punching, that's where you should be sore.
Anyway, deviated.

Save your "long distance" techniques for bridging the gap for when you have something to work with from the opponent. Don't anticipate and instigate the encounter. Wait until they commit to a course of action, then bridge what little gap there is left.
A good creedo for WC/WT: "maximum amount of effeciency, minimal amount of effort."
ex. When they kick, you C-step into their kick/stance.
ex. When they kick, you simply heel kick their kicking leg, like a door jam.
ex. When they hook punch you bridge the gap and chainpunch straight in (sometimes you don't even have to deflect, you just punch them first. Kinda messes up their hook punch )
ex. When they shoot in take the head and knee, stepping in with elbows all the way. (Until you learn the other stuff. I'm just getting into the advanced, "I won't name it because I don't feel like dealing with crap", now and I've been training 4 years) If they pick you up off the ground keep hold of that head and sit down on your butt. Use basic stance, lat sau, and chain kicking until you get up.
ex. When they straight punch or boxer's jab or feight, you shoot in chainpunching, lat sau, lop sau right there.
Always try to train the moves your learning with your hands and stepping while adding a kick. Alot of schools don't do this early or at all. But, if you chainpunch and step make sure to heel or hook kick as you do it at least once.
If you tan sau and punch, you heel or hook kick as your tan sauing.
The more you use your kicking with your hands the more devastating you will be. You'll get two attacks for the price of one.
And don't worry, the more you practice this the more power you'll develop while deflecting, punching, and kicking at the same time. It's awkward as hell at first, and you get off-balance, but like anything in MA you'll get better and more stable when you do it.
Doing this will be one of the major factors for defeating a stronger, faster, or more "experienced" opponent in the ring or elsewhere.
Keep training like you are, your an inspiration. Great job!
