I use dselect, which does update the available file and which keeps the
apt and dpkg data in sync. However, you are now over the worst of it.
Installing something would get /var/lib/dpkg/available populated.

apt/aptitude have their own idea of what packages are available and do
not use what is in /var/lib/dpkg/available. So you should not have any
problem with installing.
You could forget about /var/lib/dpkg/available and carry on as you
usually do. Alternatively, if it bothers you, either install dselect
and do
dselect update
or download a Packages.gz file and execute
dpkg --update-avail Packages
