To get Heir you need to take the talents Charming, Boon to Family, and Heir, ALL at the beginning of the game. This means you can only do it if you start with 3 talents, and if you want Treasure Hunter as well, you need 4, since to get TH you also need Alert as a starting talent. Heir gives you a special item that is appropriate for your class. Some are better than others--they range from a mid-level weapons and armor (stuff you can replace by level 10 or so) to some fairly rare and powerful stuff (bards and thieves have the best; healers and fighters are decent too).
For an Assassin, I'd recommend the missile talents--Good Shot/Keen Shot/Quick/Quick Shot/Eagle Eye/Lightning Shot. Combined, these give very nice bonuses to all missile attacks (+6 to hit and damage, 20% faster attacks, +2 speed). But that assumes you're going to be playing a missile-heavy character.
I'll echo the advice given in the Wiki article I quoted you earlier about talents: Generally, Treasure Hunter is a poor investment unless you can survive the early game (say, to Dwarftown). If you're dying a lot (or always) at the start of the game, you're probably better off with something different. The PV talent line is Hardy/Tough Skin/Iron Skin/Steel Skin/Immune to Pain, giving +3 HP, +4 PV, and +1 special PV. You need 20 To and 15 Wi to get the full benefit though, so if you don't have a good starting roll you need to train up your stats somehow. Another good option is speed line: Quick/Very Quick/Greased Lightning/Long Stride. Combined, these give you an effective +14 speed, which lets you outrun almost every enemy in the early game. Good for missile users, good for getting yourself out of bad situations.
[edit]On a Hurthling, even just grabbing Long Stride on its own (+5 effective walking speed) is often enough to make you fast enough to run away from lots of things, since Hurthlings generally start with a high enough Dx score to get 2-3 points of speed naturally.
