All the firearms you mention are excellent choices but let me mention a few others in the same vein.
If you are looking at a .22 and want something new, you may want to also consider a Ruger Mark III or 22/45 pistol. Very accurate out of the box, these can easily be upgraded to true target capability rather inexpensively. For a bolt action rifle, the Savage Mark II series are excellent as is the CZ lineup. All of these are in the 400-600 range.
If you can find a Marlin 7000 (used) in decent condition these semi-auto rifles are outstanding. Basically, a beefier 795 with a bull barrel.
The vintage Marlin 39A (mine is 1950's) is a wonderful and fun rifle and I will never part with mine. They are also easy to work on and Brownells has every part you could possibly need.
I have heard nothing but good things about Henry rifles and will eventually add one.
If you want to go with a shotgun the Browning is a nice one indeed. However, for trap you may want to look towards Remington's offerings in an 1187 or as previously mentioned 1100. Both are semi-auto and do well at trap. The Wingmaster is their upper end pump and is very nice as well.
Winchesters are excellent firearms and don't let the price of the .270 scare you away. Think of it as an opportunity to add on the reloading hobby. Not difficult and not too expensive if you go with a single stage press.
