$8 soldering iron kit, can get it at RadioShack
Assuming you have a 6-12V PSU with a barrel jack for something else lying around, http://www.sparkfun.com/products/114 will regulate for the breadboard.
I don't know what chips you'll be using, but if soldering is really an issue, you can probably get away with just 3-4 AA's in series.
Alternatively, grab an old PC power supply, jump the boot pins with a paper clip, and use the 0V and 5V pins.
Also alternatively, these exist, but I didn't find a great price on them.
DIP logic gates
There are a ton of places to get LEDs, but here's one
Like the other guy said that's 100 jumpers and is enough (but be ok with bending them).
LEDs will have a current through and voltage drop over specified, which you can use to calculate a resistor value to put in series (or just cheat) so that you can light them w/o burning them. FYI, your logic gates may not be able to drive them - I just recently tried this and could not drive a 2V 20mA LED with 150Ohm in series with an XOR gate at 5V, and I ended up using MOSFETs to drive them. I'm not an expert so just know that this might be a problem.
NAND and NOR gates are sold as NAND and NOR gates (see link above). An IC will probably have more than one gate, and will have high and low voltage source pins in addition to the gate inputs and outputs. The datasheets will tell you what the pins do.
Edit: depending on what you're doing, you may want to get another breadboard or 2 while you're at it because if you're starting out they look like they have a lot more room than they do. Amazon has them w/o the metal backing for $8 (search breadboard), and a huge metal backed kit with 4 together for $30.
