Well, if you want to learn how to solder, I suggest you to try first with some old, broken electronic devices.
They become nice "guinea pigs" when you're learning!
You need to be sure that the parts you're going to solder are clean.
If you're using new stuff, that's almost 100% sure.
Also, be sure to apply a small amount of solder on the soldering iron point.
Put togehter the parts you want to solder, heat them with the soldering iron and touch with the soldering.
I get better results when I touch with the soldering iron in one side and with the solder in the other, leaving what I want to solder in between.
As to the memories, you have the address bus, data bus and control bus, plus the power supply pins.
The address and data bus have the pins named A0, A1,... and D0, D1,...
The control bus is basically /CE, /OE and Vpp (or /WE), this last one pin is used only when programming.
Just make sure to match the pins with the proper places on the board and you're set.
More information about these can be found on the IC's datasheet, for example, most ICs need the Vpp or /WE tied to vcc to work properly.
I hope I had helped a little.
