Having made a desultary attempt in teh other direction, I feel your pain. :-(

There is an important and fundamental difference between yum update and
apt-get update. Yum update, as you say, applies patches. Apt-get update
just updates the database of packages on your computer. (I think that yum
simply doesn't do this at all.) The equivalent of yum update is apt-get
full-upgrade - but you must run apt-get update first, or you won't get
anything new. That will apply patches.

apt-cache search or aptitude search. After updating your database, of
course!!

See above.

Again, see above!

I couldn't find one in the opposite direction. :-( I just had to read up
about yum and work out the differences for myself. I fear that I gave up
rather soon. Running Fedora was just too much like trying to wade through
treacle. Especially as the book I had bought from Fedora documentation told
me zilch about the system, but explained in detail how to use OpenOffice.org.
