Hi everybody!
Like you i bought a PSTV because it was dirty cheap!
TL;DR of what you need:
1 - PS3, I absolutely need it. There are no way around sadly. I went to a friend's home to use his one.
2 - A PSN game to use as a container. The smaller, the better (for your memory card and for your transfer time). I used
Echoes (1.19€, 23Mb) but other people also used
Alien Zombie Death (1.19€, 8Mb) and
Canabalt (1.99€, 11.5Mb)
If you have both two these prerequisite you can follow a guide.
I couldn't find one that satisfied me 100%, so maybe I'll make mine sometime in the future, but on GBAtemo we have this one that is pretty good:

Just a few notes:
1) Do FIRST Part 5, THEN do Part 1 and Part 3
2) There is no need for any swap trick, just keep them on the same network and if is not recognised use a different one (I managed to do it with my phone hotspot [no authentication needed], because with my home network it was not working)
3) As soon you manage to move your PSN game from the PS3 to the PSTV, you MUST do a Backup using QCMA of your software. This way you would no longer needed a PS3 to restore it if it somehow got corrupted
4) About TN-V, to play homebrew you should use a plugin: Game2VHBL (I followed
THIS guide)
4b) In the guide it make you do a shitload of useless passages. Just load the PSPFiler (using the iso) and use an FTP client to do all the stuff he tells you to do
5) Your first homebrew MUST be an FTP Server (PSPFiler will works good), this way you can add/remove games/homebrew a lot faster and without the need to pass trough QMCA or other sony stuff (plus this way you no longer need PS Vita update blocker)
Hope to have been usefull!
