Why does bobbin thread keep snagging?
increase the needle thread tension up a bit as it is too loose to pull the bobbin thread up properly
keep adjusting until both threads are at the middle of the materials being sewn
My needle arm is stuck in the down position, won't raise manually. Newbie
Not knowing the brand and model of your machine makes diagnosis difficult. In most machines that have the bobbin case inserted from the front, you can try releasing the bobbin case and removing it. When my machine jams, removing the bobbin case releases all those threads that are twisted and knotted inside that are "holding the needle captive."

Bobbin winder screw broken, how to replace?
Until you can get your bobbin winder repaired, I'd suggest picking up a bobbin winder at your local fabric store. The last time I noticed, they cost about $30. Many sewists prefer to use this little accessory inside of wearing out the bobbin winder on their sewing machine. Also, if you more than one thread cone, you can rewind bobbins without unthreading your sewing machine.
Is it o.k. to use
Up to a point it is OK to use a heavier thread on the top with your regular thread on the bottom. If you go too heavy with the thread you might notice thread locks on the underside of material. Tightening the the tension on the top thread will usually solve this issue. However if thread is too lheavy you will not be able to adjust for tension issues. You may also find that a "too" heavy thread will catch under the throat plate. Good luck.

I'm not sure what you've actually got, since your question mentions two different machines. Straight stitch is typically the default setting (the thing that comes up automatically) on computerized or electronic machines. On other machines, there may be an indicator for straight stitch (often stitch 0 or 1 if numbered), or it may be a zigzag stitch of width 0, length whatever.
Tension settings
Some general suggestion - not familiar with White. If you know where the tensioner is, take a scrap of relatively stiff cloth in a constrasting color to the thread to make it easier to see. A good stitch tension will look like a line of adjacent dashed on top and dash-dot-dash on the bottom. If you are seeing dash-dot-dash on top and Dash-dash on the bottom, the tension is too tight. If - usual case - the bottom has dash-loopyloop-dash, or worse, snags, the tension is too loose. Remember tension may need to be adjusted for thicker or thinner work.
