If you call several HVAC dealers/servicers, you will notice that the price ranges will be across the board. I have had 3 furnaces replaced this year (80% efficiency), and I paid $1,300-$1,500 each (removal of old one, new furnace, and install). A/C will be close to that as well. If you want the contact information for my heating and air guys. Let me know.
We price homes for sale and rent. It's allways best to go to the expert! by asking this question, you might get a referral, or you can pick up the yellow pages.

You are wise to try to figure this replacement cost into your offer price, even if you decide to hold off on replacement for a while. Have you also considered asking the sellers to escrow for the replacement?(therefore you would get the appliances replaced right away)
There are also rebates out there for replacing these old appliances with high efficiency ones. Here is an example: http://www.xcelenergy.com/SiteCollectionDocuments/docs/CRS-0
In terms of your second questions about adding a new fence and landscaping, there is going to be a huge variation in costs depending what you install as well as the size of your yard, how many running feet of fence you want, etc. You could go broke on landscaping, however, if you are looking for simple yard cleanup like new sod/simple fencing/perhaps some grading, you might use a figure like 10-12K for the purpose of offer negotiation. Hope this helps.

My rough estimate to have BOTH done at the same time would be between $6000-$10,000 depending on how fancy you want to get.
But, here's the thing, you could get by without having to shell out that money right away. Both Center Point and and X-Cel energy offer home warranties on your furnace and air conditioning. The fee for the warranty is added on to your monthly bill (somewhere between $11-$20 a month). That way, they will be available most of the time to come and repair those items at no charge. And, there's also a package that would replace those items if they cannot be repaired. It might give you peace of mind to know you don't have to fork over a large amount of money in one lump sum.
By the way, what does you agent say?
Keep us posted to let us know what you decide.
I have read that a/c also can pay for itself in a reasonable length of time as the new is so efficient compared to the old. Also, the new refrigerants are cheap and the old is both expensive and not legal to make more of. That means it will cost more in the years ahead to repair and recharge if needed.
Also, different houses have different BTU needs for the hvac. The best thing is to ask a retailer and installer near you what it would cost. They should give a free quote. The difference in size of equipment needed could mean thousands of $$$ difference. PLUS the quality and warranty involved is likely to bring prices higher.
