You can, that's where these forums come into their own

Basically, more like a PVR9300T I would expect. It will need two feeds from a satellite antenna (dish

)to function (best) unlike the Freeview PVRs which use a terrestrial TV antenna (rooftop aerial

).

DVB-T2 is the second generation digital broadcasting technology for ground-based transmitters (terrestrrial TV/Freeview) to be introduced simultaneously with High Definition digital terrestrial services. Currently standard-definition digital terrestrial TV is carried on DVB-T (read DVB-T1) broadcasts.
There are roughly similar satellite equivalents, these are naturally called DVB-S and DVB-S2

No. A
Freesat HD PVR as discussed here will have the required format (DVB-S2) built-in.

No. DVB-S2 is a prerequisite to HD on satellite broadcasting and available now, DVB-T2 is a prerquisite to HD terrestrial broadcasting, available as or once analogue transmissions cease.

i and p means interlaced and progressive. In the 1080
p example, the displayed image is made of 1080 lines which are all transmitted to the screen in order, for every frame, just like when you read words from a page. With interlaced, there are two fields (half-frames) per frame, but these are not top-half and bottom-half which would result in a strange flashing effect, they are alternate scan lines, so one field contains the 540 even lines, followed by a field containing the 540 odd lines, which slot in between those in the previous field. This tricks the eye into seeing 1080 lines of detail and 50 frames (instead of 25) of movement, with half the data required to be stored/transmitted/processed.

From the specs posted above, the Humax PVR has a maximum of 1080i on the output. That doesn't mean broadcasters will offer 1080i, just that the PVR can connect to the TV at that, but not the higher 1080p.

1080p would be superior when connected to a display with 1080 lines/pixel resolution.Since broadcasts are likely to be 720i/720p, the 720p option would be better for TVs which are other than 1080 lines resolution.
