Water should not get in the bag. You will get liquid from the meat in the bag as it cooks out. It's pretty easy to not get water in ziplocs using the submersion method. Just put a slightly open bag into the cooking water, being careful to not let water in. Once the meat stops floating and most of the air is out of the bag, seal the remaining opening and ensure it's sealed. I use a large stockpot for my Anova and clip the bags to the edge, making sure water level stays above the meat.

Also usually helps to add a tsp or so of olive oil to whatever meat you're cooking.
There's a lot of conflicting info out there about adding oil/fat to bag. I think the current general consensus is that adding oil serves little purpose since you're not lubricating metal or serving as a conductor of heat, and it may actually leach out some flavor into the liquid. Serious Eats and Sous Vide Everything did some comparisons and both liked better without oil.
That being said, if you're mimicking a confit or with some stuff that sticks like fish I would definitely use it.
1. Pork Chop was a little Dry. I think that was my fault because like an idiot I listen to the box to cook Pork to 150 which is the CDC guideline but not really needed anymore. Should have gone with my usual 140F.
Definitely 140. As you've hinted at, pasteurization is a function of time + temp. All food temp guidelines are based on essentially seconds kept at that temp, not hours. Just remember when you're timing that the meat has to get to that temp internally before the clock starts and that depends on size and density of cut.
I like chicken breast at high 140s (like 149), lean pork like chops and tenderloin around 140, steaks with a lot of marbling like ribeye at 133, lean tender steaks like filet at 129, Salmon 110, beef short ribs/chuck roast for 36-48h at 136, pork ribs 142 for 36h, brisket 155 for 48h, pulled pork 165 for 24h, leg of lamb 134, burgers 125 (careful about meat selection).
3. I ended up getting the bag filled about 1/3 with liquid and when I lifted it out, there was liquid dripping from one of the corners. Assuming most of the liquid was water from the pot that got in and not the juices from the Pork. Is this a chronic issues with the Ziploc?
Honestly, I bet it was from the pork. That sucker has some juice. Especially with 2 at 150 instead of 140. You'll get less bag juice at the lower temp since the meat will expel less juice. Meats have always given off that much juice, you just don't notice when it's evaporating instantly off normally.
Hard to tell without being there, but the biggest tell for a leak is if the water color in your actual container changes (from colors in the juice given off from the protein).
