Recommending Curricula

I need some help, fellow bloggers.

I'm trying to put together a list of recommended curricula for a friend of my mother's. Here's the thing, though. She comes from a Pentecostal background. She has three children that are very close in age (10 in October, 9 in October, and 8 in January). The oldest two (10 yo boy, 9 yo girl) are both doing third grade this year (in public school). She plans to either pull them out mid-year when they move back home to Mississippi, or at the beginning of the 2011-2012 school year. She will want a Christian, YEC perspective, and a lot of things she can combine. She also is working with a limited budget; there's no way she could afford to purchase a package like MFW, WP, or Sonlight, is my understanding.

Most of this falls outside my area of expertise! Here's some thoughts I've had. Please tell me how they'd work, and offer more suggestions!

Rod & Staff grammar (I thought she could possibly start all of them in the third grade book and keep them together)
Apologia Elementary science
Mystery of History
Spelling Power (my understanding is that you need one book for all levels?)
Writing With Ease, probably starting all three in Level 1
Handwriting... A Reason For Handwriting?
Math... She (the mom) is really good at math, so she doesn't need a lot of hand-holding. At the same time, I don't think Miquon is the best fit and they're not ready for Life of Fred. What's a good basic, relatively inexpensive mid-elementary math curriculum?
Literature... I thought I'd point her towards the Ambleside Online booklists
Music - Classics for Kids podcast
Art - I outsource/d grammar-stage art appreciation. What's a good source here?

I thought I'd also mention CLE as an option to her. I don't think she's wedded to a particular approach. Her oldest has some learning difficulties (hence the reason he's in the same grade as his younger sister) but I don't know what they are/how they play out - they were caused by birth trauma (life-flighted to Memphis from Mississippi just after birth, may have had severe meconium aspiration).

Help me help her! She definitely wants to 'afterschool' until they can start homeschooling, so I'd love for her to feel like she has a good place to start. :)
