Ender-3 print issue frustration

Hey all.Hoping that someone with a bit more experience is able to help me sort my printer issues or point me in the right direction. I have an Crealty Ender-3 and Cura 3.6.0 with the Ender-3 profile.I got my Ender-3 printer about 2 weeks ago and I have been doing test prints in an attempt to sort out all the kinks and move on to proper projects. I ran the test print that came with the printer (the dog) which printed really well and only had a slight shift around layer 4. Which I was pretty happy with.So I moved onto a simple self created model and have been attempting to sort the issues/settings, but have not had very good results.So this weekend I decided that I needed to use a normal standard test print and got the All-In-One print off thingiverse and gave that a try and I noticed several issues right off the bat. I printed using the base settings for 0.2, but I did drop the size of the print down 50% (not sure if this created some of the issues?)One problem that has been consistent through all of my test prints is around layer 3-5 the external wall gets some blistering (it is even present on the All-In-One print, you can see in the front on pic towards the bottom of the print) I think this relates to the first layer of the Infill, like it is overlapping the edge too far? As subsequent layers do not have the issue. But I have modified the overlay setting and it doesn't seem to change.

In this same picture you can see there are lines between the letters, which stop once the letter layers are completed.

Flipping over to the back section, much of the finer details are just a mess (again, not sure if this is because I dropped the size down?) And I have quite a bit of stringing (first time it has done this, but my test prints didn't have a situation that stringing would occur)

The final issue I have had, which doesn't show on the All-In-One test is that, on my test print, in the same locations, almost every print, there are 3 sections that get gaps in the top layer. I have attempted increasing the layer amount, slowing the speed of the print and increasing the infill, I even tried activating Ironing (which didn't end well) but the holes are ever present.

During my test prints, I started with the basic 0.6 profile and slowly started changing settings. After failing several times, on prints 6 and 7, I took to youtube and found some "god settings" according to their creators, that "would not fail". They failed...So I am at a loss on how to identify the cause of these 3 problems (the stringing I understand, I am not sure if retraction was turned on), but the constant blistering on the 3-5 layer, the loss of finer details and the gaps on the top layer are alluding me.

I am re-running the All-In-One test today, on normal 100% size and with retraction turned on to see if this helps.I will update once this print is completed.Thank you for any help and insights you can provide.
