First off, RELAX some! Yeshua said his burden is light and His yoke is easy - and it is!
Bibles - hmmm.....Not a one of them is a perfect translation, but there are some that are better than others. I love the way the CJB reads but the font is so very small in mine (the leather-bound) that I rarely use it, and never carry it with me. The NASB is supposed to be the closest to actual translation but is difficult to just read. For doing just normal reading my preference is NIV (easy on the words chosen and large font).
This is all with the NT in mind, I don't use any Christian OT at all.
For the Tanakh I use the Artscroll Stone Ed. 2007 bible. I love the wording, the font is almost large enough and the commentary is good.
Next, lifestyle. I don't know of any true Torah-observant Messianic, Jew or gentile, who doesn't follow kashrut to some degree or another. I started off with the very basic, no pork, no shellfish, and that was about all I cut out of my diet at first. But with that "willingness" the Spirit led me further and 8 years later He's still leading me.
ALL of your lifestyle changes is in baby-steps. God does not expect his babies to be able to run with the "grown-ups!" To this day, if I am going to take a new dish to worship service I call someone to check that all the ingredients are "kosher," I'm still learning. If I cannot reach anyone, I'll bring a bag of chips.
Much in the 613 are not actually mentioned in the NT, but that's not because they are not valid, but it was expected that all those things would be learned weekly in the synagogues by the gentiles coming in. The four "requirements" mentioned in Acts was simply to make the gentiles able to join in the worship at the synagogues and table fellowship immediately.
Again, observing the Shabbes is like going kosher. Baby-steps. I'm still learning about the day. So far, for me, it's a 24hour giving back to Adonai. I don't handle money on that day, I don't surf the web or go outside my home for my own pleasure. In other words, all my activities are geared toward study of His word and worship. I will drive to synagogue but no where else, I will come into forums or websites that have live feeds or chat rooms to fellowship but I don't "surf" the web, and I do no financial business on Shabbes. I prepare my meals and snacks for Shabbes on Fri., and make sure all business is finished by late Fri afternoon. Again, it was baby-steps and I'm still learning.
The Holy Days most assuredly should be observed. They are little memorials/rehearsals of what has or will happen. They are fun and informative. Stay tuned to the forum and as each feast rolls around you will see threads popping up with questions on each one. The next one that is coming (there are 3 more in very quick succession) is Yom Teruah. Google that and you can get a jump on it, or just check out Judaism 101.
Here is a link to El Shaddai Ministries teachings page (scroll down a bit to the feast services recordings), you might find these helpful:

(Keep in mind, my offering this link is not an endorsement that the teacher is 100% correct 100% of the time, only that his teaching is pretty sound. And that's about all we can hope for nowadays....)
But, you know? it's all been a joy, not oppressive at all. No one is in a "I do it better than you" attitude at all. Everyone is learning. And we all love to share what we've been taught!
Your last four questions are debated among messianics. Most have no problem with the term "rabbi" being used, some do. Women teaching is about 50/50. Images: photos, statues, TV - most of us don't use photos or statues, I would say most would be against these. TV, I'm not sure I understand....? could you elaborate? The 10 commandments? yes, definitely we should obey these.
