With manufacturers migrating to UHD/4K, 1020 sets are getting hella cheap. I saw a 65" Sanyo at Wal-Mart over the weekend for $990-ish and 50" sets for under four bills. Stick with 1080p as a minimum.
That being said...
1) Don't worry about resolution so much as refresh rate. A higher-resolution set with a crappy refresh rate will look worst than a pseudo-HD set (720) that has good refresh rates and pixel quality. Get one with at least a 120 Hz refresh rate if your budget can swing it. Otherwise, get a name-brand unit. They will likely have better imaging engines that will make a 60 Hz refresh rate less prone to pixellation and motion jaggies.
2) Get the Blu-Ray player. The only advice I can offer here is that you
will eventually need to upgrade the firmware. You might even want to use it for streaming. Who knows. In either case, if you're near a network jack any player will do, all you have to do is plug in and go. If you don't have a handy network jack the be sure the player has included wifi. Be careful here... some makers will call their stuff "wifi enabled", meaning you can get wifi IF you buy their extra dongle. Make sure it say "wifi included" or something similar.
3) There is nothing magical about an HDMI cable. The Monoprice and AmazonBasics units you can get two for ten bucks on Amazon will work exactly as well as the $20-a-pop cables at Best Buy. Same goes for surge protectors. You can get two excellent ISOBAR surge protectors from Amazon for the same price as the ho-hum LOOKITMYPRETTYPACKAGE!! unit at Best Buy.
4) Run to Best Buy or your local electronics warehouse and look at the TVs. It'll blow you mind what you can get these days. Look especially hard in their clearance and open-box section. The last two sets I bought were Best Buy open-box units. One had a little scratch on the bezel which no one but me has ever noticed, the other was returned because it was too big for the customer's entertainment center. A full third off the regular price and still with a perfectly intact factory warranty.
(edit to add)... Aldo be careful about the number of inputs. With the proliferation of home theater systems that switch inputs before they ever reach the TV, manufacturers have started scaling back the number of HDMI inputs. You want at least three. This is running under the presumption that you will have, at some future point, a disc or media player plus some type of cable or streaming service box. This leaves one port free for expansion or for when some family member with a gaming console shows up for the weekend.
I have the previous model to this TV and have been
very happy with it, including use with blu-ray and console gaming setups. The only difference is mine was about twice this price when I got it two years ago.
