That would be a great starter set of tools. Knowing how to use them is good. Lots of the basic things on a bike are easy enough to teach yourself or learn off of sites like Sheldon Brown's.
Lights are dependent on what type of riding you do at night. In-town riding does not, necesarily, require the type of lights we use when riding trails. I use an HID light for trail riding at night, but felt fine when I used a $25 light in-town. The $25 light would be horrible on the trail (not bright and doesn't last...).
Pumps, I love my Crank Bros. I am also fine with my $15 one I bought from a department store when I couldn't find my Crank Bros pump while on a road trip. A couple of riding buddies love their Topeak Hurrican (?) pumps.
I don't use a seat bag any longer. I keep all of my "stuff" in a backpack when I ride (CamelBack HAWG or DaKine). I keep a multi-tool (Crank Bros 17), tube patch kit, two extra tubes, my water bladder of course, tire wrench, pencil, duct tape (strong all purpose tape), matches, food, etc in it.
I really like the T-9 lube (made by Boeing?) and the Pedros stuff for lubes and/or cleaning. Pedros makes a good biodegradeable degreaser (smells good!).
I love having a decent bike stand. That and the wheel truing stand have been my most favorite bike tool purchases/trades. They have proven invaluable.
Good luck and welcome aboard.
