hiya!!
dont wanna sound all bossy but dont use an old fashioned scrapbook, many are not photo safe. You'll need an album that's acid and lignin (sp) free.
You'll need card(stock) as a basic and paterned paper is really nice to have - although not a necesity, i cant enuff of PP tho and have far too much LOL.
get some A&L free adhesive - a glue stick, craft glue, double sided sticky tape, glue gun, glue runner.... the list is endless.
journalling can be done by hand or you can print it off. If you want to write on the photo's you'll need a photo safe pen(s). Archival pens are best as the writting wont fade for years.
then embellishments!! yummmm!! cant get enuff of these either!! did i forget to say i was a stash hoarder??
just go for bits that you like - brads, buttons, blooms, sequins,rub ons, bling, ribbons/rikrak/trim again an endless list
You can use stickers, hand cut or die cut letters cut from card or PP, chipboard (very popular at th moment) rub ons.....
theres tons of disney themed stash that you can buy let me know if you need links or you can do an internet search.
can you tell i get a little excited talking about scrapping?
another idea, you could make a minibook to have a hand ready keepsake.
there's so many different types of minibooks you can make/buy
oh and if you are a bit daunted by scrapping in 12x12 you can always try 8x8 or 8x11.5 or even a4
just yell if you need me to waffle more
