apt-cache policy is handy for checking exactly what version of a package you have installed. and if you do an apt-get update first it will also show what the available version is for the package... it will also show which repository the packages are coming from..
heres an example
Quote:
debian:~# apt-cache policy mysql-common
mysql-common:
Installed: 5.0.18-8
Candidate: 5.0.18-9
Version table:
5.0.18-9 0
500 ftp://debian.uchicago.edu unstable/main Packages
*** 5.0.18-8 0
500 ftp://ftp.uwsg.indiana.edu unstable/main Packages
100 /var/lib/dpkg/status
debian:~# apt-cache policy xserver-xorg
xserver-xorg:
Installed: 6.9.0.dfsg.1-4
Candidate: 6.9.0.dfsg.1-4
Version table:
*** 6.9.0.dfsg.1-4 0
500 ftp://ftp.uwsg.indiana.edu unstable/main Packages
500 ftp://debian.uchicago.edu unstable/main Packages
100 /var/lib/dpkg/status

Someone already answered your dist-upgrade question.. theres more of an explanation in man apt-get.. basically dist-upgrade is a bit more agressive in dependancy handling than upgrade..
I run sid so I'll get a number of packages that are held back when I do normal
apt-get upgrades, so occasionally I run
apt-get dist-upgrade to get those packages that have been held back to install / update..
