Yes depending on how many different types of electronics you are trying to hook it up to. The more electronics, the more expensive of a universal remote you'd have to buy.

1080p
The PS3 works best when connected to the 1080P HDTV with HDMI cables and the new slim PS3 may then even allow your HDTV remote to Play the Blue-Ray movie that you also need to get Blue-Ray. I know with my PS3 slim 120 GB model connected with HDMI cables to the Sony BR6 HDTV I can use my HDTV remote for Blue-Ray and DVD movies played in the PS3.
1080p is the highest standard of HDTV.
Forza 4 can be displayed at 1080p.
you need a HDMI cable and 1080P media like a Blue ray disc and a HDTV with 10080P capabilities before you will receive full 1080P. For example most HD TV programing is only 720P and will not be in full 1080P on a 1080P HDTV and a TV show in 480i standard will be in 480i on a 1080P HDTV
1080P is the highest quality HDTV.
the one that plays 1080p
Yes the PS3 supports 1080P when it is connected to a 1080P HDTV with the correct connection cables. The blu-ray disc plays movies at 1080P when played on the PS3 to my HDTV. The PS3 also upscales DVDs to near HD quality with amazing results. In order to fully support 1080p you do need to have a 1080p capable HDTV connected to the PS3 with HDMI or component cables.
One can buy a 1080p television at the store Target, for example. One should keep in mind that a 1080p television does not improve ones viewing experience unless one has access to video content shown in 1080p.
