Phil - do you prefer enamel or acrylic? if you use acrylics or just don't mind them Color of Eagles acrylics are GREAT!!! they airbrush on like you wont believe and give an incredible flat surface when painted even after masking!!! Just noted that because you were looking to order your paints online and I believe it is Great Models that is stocking them now... Before the only place you could get them was the hobby shop... They are Vallejo paints repackaged..
You'll love that Tamiya F4F!! although a little simplistic on the inside (I recommend the Ultracast seat at the least.. the wheels if you want to do more) it turns out to be a good looking model and goes together like a charm! The only part you really have to pay attention is the landing gear... study the drawings and make sure when you put it together you have it facing you the same way as the drawing in the book and the slots are facing the same direction (up or down) the rest is cake!!
Here is my Wildcat crossdressed in British clothing... The F4F was the first US built aircraft to down an Axis plane im WWII.... a Ju88 over Scapa Flow somewhere... scroll down towards the bottom of the page... you'll see it...

---edit---
when you get ready to build the SBD come back here and ask us if you have questions, I know Jeeves and I have built several so it might make some parts easier...
you might want to set aside some time on the cockpit as well...
