You could also check out anniemodesitt.com for a good basic course
in combination knitting. What I generally do is when a pattern calls
for ssk I just k2tog but when it calls for a k2tog I reposition the
stitches on my left hand needle to be in the "regular" position and do the k2tog as one would normally do it in standard western style knitting. On increasing I don't do anything different as there are so
many ways to do increases I usually just use whichever one looks
best with whatever I'm knitting. As far as I know, increasing generally
doesn't require the special maneuvering that decreasing does but
I'm certainly no expert on the matter!
