It sounds like you may be like me with your skin type.  I have found that it I use a good face wash (Currently Neutrogena Even... something foaming cleanser) and a good moisturizer I have cleared up a lot of the problems you mention.  The oiliness actually comes from your skin reacting to the excess dryness.  I haven't really found a moisturizer I like yet but I have been using a sample of Garnier nutritionist and I really like it.  One that is thick yet not oily that contains an anti-wrinkle/anti-aging component is yor best bet.  I think you may find the acne subside a little once you get that under control.  A cleanser that really worked well for me was called Ambi though I can't find it at my store anymore.
