I am a SENCO (although not in pre-school) - we invite parents to "formal" IEP reviews twice a year. This is usually one or both of the parents, with me, and the class teacher. We look at the targets from the previous IEP, and where appropriate, the teacher will show the parents evidence of progress made against the targets. If we agree that a target is being reached, then we will amend the target or take it to the next level. When the new IEP is written we discuss how we can work together to help the child with thier targets, so parents know what the best approach is at home, and so on.
I would imagine that in a situation where the school know that your child will be leaving soon, they want to make sure that thier IEP is as up to date as possible so that the new school don't spend time covering old ground. I think it's a great idea for your current school to have discussions with the new school about your child - I usually do this with the secondary schools towards the end of the Summer term, and will always contact the previous school of a new starter (or the class teacher will)
Also, as stated earlier, if you have ideas about targets, great! Schools generally want to work with parents, not against them, and the kind of things that you have suggested sound sensible and manageable, and would be easy to include as Early Years targets, which are often practical, rather than academic, and are also more tangible and measurable.
Good luck with your meeting, if you need any other help, I would be happy to assist (on Maternity Leave and need to keep my brain ticking over!)
