[COLOR="#300090"]You have most of the base stitches listed; here is a list off the top of my head.
sl st—Slip stitch: used to join in the round
(I think it looks similar to a duplicate stitch in knit)
Base stitches: (In order of increasing height)
1) SC—Single Crochet
2) HDC—Half-Double Crochet (1 YO to start)
3) DC—Double Crochet (1 YO to start)
4) Tr—Treble Crochet (2 YO to start)
5) DTr—Double Treble Crochet (3 YO to start)
6) TrTr—Triple Treble Crochet (4 YO to start)
The numbers show the number of chains needed to rise to the height of the stitch (such as in a turning chain).
(as listed on NexStitch)
Back Cross Stitch
Double Sol. Knot
Front Cross Stitch
If you find a pattern that uses these or perhaps other fancy stitches, then the pattern should also tell you how to do the stitch.
[Magic ring or magic loop](http://www.geocities.com/Heartland/Cottage/3606/knowhow1.html#Beginning a ring with a loop)* (*crochet version) are for in the round.
That is a link to Daphine's Tutorial page which has drawings and instuctions for the magic ring.
The Magic Adjustable Ring: A Better Way to Begin Crochet in the Round by Donna Hulka at CrochetMe.com has nice illustrattive photos.
