It looks to me like if the mounts fit, they can be used. There may be some issues with some of the settings (will have to try them all to see if they work).
When I bought my DSLR, they had a special going on and I got 2 lenses free along with a carry bag and a filter as well. You may be able to find a similar sale especially after Christmas!
Your best bet might be to talk to a well known photography store that knows a lot about specific cameras and lenses. How about taking your 35mm lenses with you when you shop for your new DSLR and try them out before buying.
Good luck with the shopping. I love my DSLR and wish I had more time to go on shoots.
