We are going to need more details than that to make any recommendations. I am assuming you mean a a/v receiver for the home theater? There are now a fair number of good a/v receivers with hdmi in and out (most have only 2 in though so if you have more than 2 hdmi devices you will need a hdmi switch as well and luckily they do not run too much).
No idea for advice about wireless speakers as for the most part they do not have anywhere near the same quality as wired speakers. Someone here may have used some good ones to point out.
Agree with sjr.
In my many years of being in the A/V hobby there are four factors which dictate the ultimate system you end up with. In order of most influence....WAF (wife acceptance factor), budget, room, and performance. With the information posted by the OP, there isn't enough to go on.
A comment on wireless speakers......don't. Unless you absolutely cannot have wired speakers, I haven't seen any wireless speakers approach the performance of even mediocre wired speakers. Plus the whole wireless speaker name is misleading. You still have to run a power cord to power the RF electronics and amp of the wireless speaker. So you have to find a wall outlet to get power to the speakers. If you're going to do that, you might as well just run the necessary speaker cables. Remember, pulling power cords behind the wall is against building codes.
