Julie (and others who asked questions in this thread),
We are currently over halfway through the Foerser's Algebra with our second oldest son, and I want to assure you that you will have no need to add anything to it! It is a very solid, very well-written text that definitely goes even beyond the word problems that we did in Singapore math when we did DM 1A/1B last year. Plus, the Foerster text does not make leaps like the DM texts did (often leaving us scratching our heads to discover why they did what they did)!
The first few chapters of Foerster are actually pre-algebra, rather than algebra. They are meant to give students a needed foundation prior to moving on to harder concepts, so don't judge the Foerster text until you get a ways beyond the opening few chapters. As you are already aware, math at the high school level is very different from math in elementary/middle school. It requires a shift in thinking (and in teaching) no matter what text you use!
I found this when we did VideoText Algebra with our oldest son and now again as we are doing Foerster Algebra with our second son.
As far as the other questions asked in this thread go, I do meet with my son and we read over the examples and discuss them together. Then, there is usually an oral part which we do orally together. Then, I assign him the odd problems only (which is what Foerster actually recommends in his Introduction). We did do all of the story problems for every chapter until chapter 6 or so. Then, we began doing only the odd story problems (as the problems become much more involved). I haven't found the need yet for the Math Without Borders DVDs at this level, however your need will depend upon your comfort level with Algebra. The DVDs are a wonderful teaching tool available as needed. The fully worked Solutions Manual is invaluable at our house!
We usually take 1 hour to do math and are able to complete a lesson daily in that amount of time on most days. Sometimes it is longer. The problem solving sets we spread out over 2 (or even 3 days). We are enjoying Foerster's Algebra I.
It is not meant to be a text to hand to your child though. It does require parental oversight and guidance. Truly, any program that says it is self-teaching for math is making quite a claim (in my opinion). Usually most "self-teaching" programs for high school math end up requiring the parent to get involved when the child hits a roadblock later. By then, the parent/teacher is so far out of the loop as far as what the child is learning in math that the parent isn't even able to offer any help (except to consult the answer key).
I had this experience with VideoText Algebra (even though I knew I was supposed to watching along with my son and interacting with him daily). Somehow, I lost track of what he was learning and later was unable to help him without the answer key.
This is why I think it is a good goal going in to high school level math to spend time with your child daily on this important subject. With Foerster Algebra I, I go through and discuss the provided examples with my son, go over the oral examples, and make sure my child gets started right. We keep the Solutions Manual close at hand, and I check in with him as he works. Some days he needs me more than other days.
In the Introduction to the World Geography guide, we do give an overview of how to pace Foerster Algebra I. The only change I've made to the pacing I mentioned there is to now go to doing only the odds of the story problems now as well.

Foerster's Algebra I is often considered honors level; however, your child won't have to be a math whiz to use it, because everything is explained so well! I've never seen an Algebra text with more thorough step-by-step examples. It truly was a relief to go to Foerster after DM 1A/1B for my math-loving son for this very fact. While we originally loved DM, by the time we were close to finishing 1B we had reached a frustration point. Our lessons were taking much more than 1 hour, and I was spending more and more time helping my child through every part of the lesson. We were quickly becoming burned out on math, when it had previously been a favorite subject.
While Foerster's Algebra I is by no means easy, it does very solidly teach each concept. This keeps frustration at a minimum. The examples are outstanding and the word problems really get students thinking. I highly recommend this text! Just be prepared to go through the examples with your child on most days and help as needed as your child works.
I will say that for students who have a very difficult time with math, No-Nonsense Algebra would be a better choice.
This is why we offer several Algebra recommendations at HOD to help families find the one that fits their child best.
Blessings,
