Since I rarely have to restore transaction logs, I might be missing
something, but there is a screen in Enterprise Manager which looks
spot on target. Right-click databases, select All tasks, and then
Restore. In the dropdown "Show all backups for all databases". Select
the database you want to restore backups for. In the box below, the
full backups and the log backups will appear (and I assume the
differential.)
I will have to admit never having tried it, but I'm pretty sure that
I did something like this in 6.5 days, and I can't see why MS would
drop such a feature.
If you want to look at scripts, this could be a starter:
