My help offering might be your thing - or not.
DPN are really easy - once you get them.
if you want to finish something before you get it all... work 3 or 4 rows before joining, then sew that tiny seam afterwards. With that many rows it is easier to see and you can get used to the rest of knitting on DPN - and have a finished project at some point.
if you want to start the real thing, do it like this:
you cast on, you turn all your stitches towards the middle - then join.
do not put your work down until you made 3 or 4 rounds! this way there is less likelyness to twist things.
hold your work with the right side out (since you work the right side). hold it like the top rim infront of you and imagine this would be a cup you drink from. The working edge will always be on the point you drink from the cup. Then you always know where to knit to: your stitches are on the left needle before you work them and on the right, after you work them. (just like in "normal" knitting).
if you have trouble to remember the right side of your work: mark it. It may be hard for beginning knitters and for the knitters that can not read their knitting easily. And for all knitters, when they work a piece with 2 equal sides....
I have come up with multiple ways of marking the right side. One way is to tie in a piece of string that only shows on one side of the piece or a string that you tie to a noticable bow on the right side.
if your knitting is made with a little larger stitches: how about cuff-links... well: take 2 different buttons. Remember which one you want on right side - write it down if necessary. Then button them into the piece after you have made a few rows... it is real easy then to see where the right side is.
what helps me is to keep my needles "ordered" right for working them.
the needle I work with (right hand) is infront of everything, of course.
and the left needle I work off of I place BEHIND the next needle in the round.
Something I imagine that could help to not twist:
after casting on, pull pieces of waste yarn around the cast on edge about twice on every needle
trail them off of the piece,
now pull on them so the cast on edge is oriented to the middle everywhere and there are no twists.
join the round.
then tie them all together.
imagine a basket: your cast on is the top edge. Now you close the bottom of the basket with these strings.
if you WOULD twist now: you would REALLY see it.
to orient your knitting right: pull on those strings / the knot. and everything is all right!
